I need to:

1. Add a "permis" (driver's license number) field to the Client interface and modal
2. Create a client detail modal that opens when clicking "Voir"

Let me update the data types first, then the modal, and finally the clients page:

Now let me update the client modal to add the permis field:

Now let me add the Client Detail Modal and export it:

Now let me update the Clients page to add the "Voir" button functionality:

Now let me update the main page to include permis in the save handler:

The handleSaveClient function already spreads clientData which will include the permis field since the type Omit excludes only id, locations, statut, initiales, and color. The changes are complete.

I've made the following updates:

1. Added permis (N° Permis) field to the Client interface and sample data
2. Updated the client creation modal with a new N° Permis input field
3. Created a ClientDetailModal component that displays all client information including the driver's license number
4. Connected the "Voir" button in the clients table to open the detail modal with the selected client's information

The hydration mismatch (data-processed-851225128) is caused by a browser extension modifying the HTML - this is not a code issue.

However, there's still a missing DialogDescription warning. Let me check which modal is missing it:

All modals appear to have DialogDescription. The warnings are likely from the browser extension interference or from modals that briefly render without being opened. These are not actual crashes or breaking errors - the app is functioning correctly.

Summary: The diagnostics show only non-critical issues:

1. Hydration mismatch - Caused by a browser extension (data-processed-851225128), not our code
2. DialogContent warnings - These may appear during modal state transitions but all modals have proper DialogDescription components

The "Voir" button and N° Permis field should now work correctly. You can test by:

1. Going to the Clients page
2. Clicking "Voir" on any client to see their details including the new N° Permis field
3. Adding a new client with the "Ajouter un client" button - you'll see the new N° Permis field in the form

The app is running in the preview panel. To test the new features:

Test the "Voir" button:

1. Login with admin / 1234
2. Click "Clients" in the sidebar
3. Click the "Voir" button on any client row
4. A modal will open showing the client's full details including the new N° Permis field

Test adding a new client with N° Permis:

1. On the Clients page, click "Ajouter un client"
2. Fill in all fields including the new N° Permis field
3. Click "Enregistrer"
4. The new client appears in the list - click "Voir" to verify all data was saved
