I'll add the Subscription (Abonelik) functionality to both the Contract and Account pages. Let me first read the existing files to understand the current structure:

Now I have a complete understanding of the current structure. Let me implement all the changes:

1. First, I'll create the Subscription tab component for the Contract page
2. Update the Contract content to add the new Abonelik tab
3. Update the Contract side panel to add the BAĞLI ABONELİK card
4. Update the Contract banner to handle subscription-related status messages
5. Create the Subscriptions tab for the Account page
6. Update the Account content to add the new Abonelikler tab

Now let me create the Subscriptions tab for the Account page:

Now let me update the Account content to add the new Abonelikler tab:

I've implemented all the Subscription (Abonelik) functionality as specified:

Contract Page Updates:

1. Side Panel - Added "BAĞLI ABONELİK" card with green left border between "BAĞLI FIRSAT" and "ONAYLI TEKLİF" cards, showing subscription details (name, ID, status badge, dates, remaining days, component count, vehicle count, occupancy percentage with progress bar) or empty state message
2. Tab Bar - Added "Abonelik" tab between "Kontrat Kalemleri" and "Yenileme Zinciri" with dynamic status badge (Aktif/Beklemede/Sona Erdi/Iptal Edildi)
3. Quick Actions - Added conditional "Aboneliği Görüntüle" or "Abonelik Oluştur" button with green styling, disabled when contract is cancelled or ended
4. Banners - Enhanced to show subscription-related status messages when contract is suspended, cancelled, or ended

Account Page Updates:

1. Tab Bar - Added "Abonelikler (N)" tab after "Kontratlar" with dynamic count
2. Tab Content - Table view with summary stats, filters (dropdown selects), and 5 columns (Abonelik No, Abonelik Adi, Durum badge, Baslangic, Bitis) - all values are static text (not clickable links as specified)
3. Empty State - Shows centered message with icon when no subscriptions exist (no CTA button as specified)

Now I have the full specification. I need to:

1. Create the Abonelik (Subscription) detail page at /abonelik
2. Update navigation links in Contract and Account pages to be clickable

Let me start by creating all the components for the Subscription detail page:

Now I need to update the navigation links in the Contract and Account pages to point to the Subscription page. Let me update the relevant files:

Now I need to update these files to make the navigation links active. Let me update all three files to enable clickable links:

Now let me update the Contract's subscription tab to enable the navigation:

Now let me update the Account's subscriptions tab to make table rows clickable:

Now let me also update the subscriptions data to use the correct master demo data (ABN-00000234 instead of ABN-00234):

I've completed all the implementation:

Created the Abonelik (Subscription) Detail Page at /abonelik with:

• Red top header bar with breadcrumb showing Account > Contract > Subscription navigation
• Header card with subscription name, ID, status badge (Aktif), KPI cards (Süre, Kalan Süre, Bileşen Sayısı, Araç Sayısı), and occupancy progress bar (34%)
• Green status banner indicating active subscription with 412 days remaining
• Status timeline showing lifecycle stages (Taslak -> Aktif -> Beklemede -> Sona Erdi -> Yenilendi)
• 5 tabs: Genel Bilgiler, Bileşenler (3), Araçlar (247), Kullanımlar, İşlem Geçmişi
• Right side panel with linked record cards (BAĞLI KONTRAT, BAĞLI HESAP, BAĞLI FIRSAT, BİRİNCİL KONTAK, KAYIT SAHİBİ, HIZLI AKSİYONLAR)

Updated Navigation Links:

1. Contract side panel "Aboneliğe Git" button now links to /abonelik
2. Contract subscription tab "Abonelik Detayına Git" button now links to /abonelik
3. Contract quick actions "Aboneliği Görüntüle" button now links to /abonelik
4. Account subscriptions tab - table rows are now clickable with soft red hover effect, and Abonelik No / Abonelik Adı columns are blue links to /abonelik
