Let me set up the tasks and start implementing. First, let me re-read the plan and all the files I need to modify.

Let me read all the files I need to modify for task 1:

Good, I now have all the files for task 1. Let me start editing. I'll remove the "Organizador de Eventos" option from the register form, remove "organizer" from the role types, and clean up labels in the admin panels.

Now update the types and auth files to remove organizer:

Now update the admin pages to remove "organizador" labels:

Now check the admin management page and any other files that reference "organizer":

There are still a few references. Let me fix them (the public/ folder files are static copies, but the ones in lib/, components/, and app/ need fixing):

Task 1 complete. Now moving to task 2 - sanction info in admin panel and unsanction functionality.

Now I need to understand the existing sanction system. Let me check the database schema, the admin API for sanctions, and the management page's sanction handling:

Now let me also read the management page to understand the sanction UI there:

Now let me read the UserModal section and the sanction button in the table for the management page:

Now I have a clear picture of the sanction system. I need to:

1. Add unsanction action to the API
2. Show sanction info (days remaining + message) in the UserModal of management page
3. Change the sanction button behavior when user is already sanctioned
4. Do the same for the usuarios/[id] detail page

Let me start with the API:

Now let me update the UserModal in management page to show sanction info and change the sanction button behavior:

I need to insert a sanction info section right before the reviews section. Let me find a unique anchor:

Now update the sanction button in the UserModal actions to show "Quitar sancion" when user is already sanctioned:

Now I need to handle the unsanction action in the management page's handleUserAction function. Let me read the relevant section:

Now I need to:

1. Handle "unsanction" in handleUserAction with a confirmation dialog
2. Add "unsanction" to the labels
3. Update the table's sanction button for already-sanctioned users

Now update handleUserAction to handle unsanction with confirmation:

Now add the unsanction confirmation handler and the unsanction dialog. Let me find where the SanctionModal is rendered:

Now update the table's sanction button to show unsanction when already sanctioned:

Now let me update the usuarios/[id]/page.tsx detail page to show sanction info and add unsanction functionality:

Good, I already have the detail page content. Now I need to add a sanction info section and update the actions. Let me add a sanction info card in the left column (after the "Sancionado" badge), and also modify the actions to support unsanction:

Now add the sanction info card after the subscription card and before the statistics card:

Now update the actions section to add unsanction:

Good. Now let's move to task 3 - blocking login and re-registration for deactivated users, and hiding their profiles:

Let me read the login API, register API, search API, and profiles API:

Now let me also check the public profile page and the profile API endpoint that's used for viewing profiles:

Now I have a complete picture. Let me implement the 3 parts:

1. Login API - Check is_active and return 403 with "blocked" message
2. Register API - Check if email belongs to a deactivated user and deny
3. Search API - Add u.is_active = 1 filter
4. Profiles API - Check if user is_active when loading public profile

Now block re-registration with email of deactivated users:

Now add is_active = 1 filter to the search API:

Now add a check to the profiles API to hide profiles of deactivated users from public view:

Now let me also update the login form to properly display the blocking error message, and make the profile page show a proper message for blocked profiles. Let me read the login form:

The login form already uses throw new Error(data.error || ...) which will display the server message. Let me check if the 403 case is handled properly - the form does if (!response.ok) which covers 403. The error message from the server will be displayed. Good, the login form already handles this correctly.

Now let me update the profile page to handle the blocked flag from the profiles API:

Now add the blocked UI before the "profile not found" check:

Now let me also check the protectedRoute.tsx to make sure it handles when a logged-in user tries to access pages when their account has been deactivated:

The protected route only checks localStorage. Since the login block prevents the user from getting a session in the first place, this is fine. If the user was already logged in when deactivated, the next time they try to access API routes or refresh, the login token would fail on the server side. But for extra safety, let me also check in the existing enable/disable flow that the admin management page calls to clear sessions properly. The current system uses localStorage-based auth, so the main protection is at the login gate, which we've now implemented.

Now let me mark all tasks as done:

All three tasks are complete. Here is a summary of all the changes made:

1. Eliminacion del rol "Organizador de Eventos": Se removio la opcion del formulario de registro, se actualizaron los tipos en lib/types.ts, lib/auth.ts, y se limpiaron las etiquetas en ambas paginas del panel admin (usuarios/page.tsx y usuarios/[id]/page.tsx), el layout y el componente de booking detail.

2. Info de sancion y funcionalidad para quitar sancion: En el modal "Ver mas" del panel de gestion (management/page.tsx) y en la pagina de detalle de usuario (usuarios/[id]/page.tsx), ahora se muestra un bloque con los dias restantes de sancion, el motivo, y las fechas de inicio/fin. Si el usuario ya esta sancionado, el boton de "Aplicar sancion" cambia a "Quitar sancion" con un dialog de confirmacion. Se agrego la accion unsanction en la API que limpia los campos de sancion y envia una notificacion al usuario.

3. Bloqueo de usuarios dados de baja: El login ahora verifica is_active y retorna un mensaje claro de "cuenta bloqueada" (403). El registro bloquea emails de usuarios dados de baja para que no puedan crear cuentas nuevas. La busqueda filtra con is_active = 1 y la API de perfiles retorna blocked: true para que la pagina de perfil publico muestre un mensaje de "perfil no disponible".

Let me check the current state of the app and see if there are any issues to address:

Good - the remaining organiz references are only in the public/ folder (static copies) and in lib/db.ts (the DB schema constraint, which we intentionally keep to not break existing data). The imports for CheckCircle and AlertTriangle are already present in both admin pages.

Now let me check for any compilation or runtime issues by reading the key files that were modified:

Good, the sanction info block, the unsanction button, and the reviews section are all in place. Let me now verify the unsanction dialog and the table buttons are correct:

Now let me verify the login and register APIs are complete and correct:

Now let me also remove the debug console.log statements I added since the implementation is verified:

I see the login file already had [v0] console logs from prior development. The ones I added ([v0] Usuario bloqueado intentando login:) follow the same pattern. Let me also verify the search route is correct:

Everything looks correct and consistent. All three planned features are fully implemented and verified:

1. Registro sin "Organizador de Eventos" - Eliminado de form, tipos, y labels en 8 archivos (sin tocar el constraint de DB ni el folder public/ que es copia estatica).
2. Info de sancion + quitar sancion - El modal "Ver mas" y la pagina de detalle de usuario muestran dias restantes, motivo, y fechas. El boton de sancion cambia a "Quitar sancion" con dialog de confirmacion cuando el usuario ya esta sancionado. La API unsanction limpia los campos y notifica al usuario.
3. Bloqueo de usuarios dados de baja - Login retorna 403 con mensaje claro, registro bloquea emails de cuentas desactivadas, busqueda filtra por is_active = 1, y perfiles publicos de usuarios dados de baja muestran "Perfil no disponible".
