• Contributed by @Swe-HimelRana

BDT Currency Support (#92)

• Contributed by @Swe-HimelRana

Cancellation Date Email Notifications (#88) ⚠️ NEEDS TESTING

• Get notified before subscriptions end (cancelled services)
• Email and Pushover notifications for upcoming cancellations
• Configurable reminder days (1-30 days before cancellation)
• Daily scheduler checks for subscriptions ending soon
• Settings UI matches renewal reminders design
• Mirrors renewal reminder architecture for consistency

🧪 Testing Needed: This is a new feature that mirrors the renewal reminder system. While the code structure is solid and all tests pass, we need real-world testing with subscriptions that have cancellation dates set. Please help test by:

1. Setting up email/Pushover notifications in Settings
2. Creating a test subscription with a cancellation date 3-7 days in the future
3. Verifying you receive notifications as expected

Technical Changes

• Added CancellationReminders and CancellationReminderDays to NotificationSettings model
• Database migration for cancellation reminder tracking fields
• New repository method GetUpcomingCancellations()
• New service methods SendCancellationReminder() in email and pushover services
• Cancellation reminder scheduler in main.go (runs daily)
• Settings handlers for cancellation preferences
• New Pushover service with comprehensive test coverage (406 lines)
• Currency integration tests added
• Updated documentation (README, AGENTS.md)
