feat: remove default account mapping and implement offline-first account mirroring

This commit removes the confusing default account mapping feature and implements a more reliable offline-first account mirroring system. The changes include:

BREAKING CHANGES:
- Remove all default account mapping functionality (saveDefaultAccount, getDefaultAccount, etc.)
- Simplify account selection to use direct account choice instead of default mapping

FEATURES:
- Implement account mirroring system that stores all FireFly III accounts locally
- Add offline-first approach: server accounts > mirrored accounts > fallback
- Automatic account sync when connection is available
- Manual sync capability in config screen
- Enhanced offline reliability - app works completely without server connection

IMPROVEMENTS:
- Faster startup times using local account cache
- More predictable account selection behavior
- Reduced confusion about which accounts are being used
- Better error handling for offline scenarios
- Simplified architecture without complex default mapping logic

+## [2025-11-17 11:57] - Remove Default Account Mapping Feature and Implement Offline-First Account Mirroring
+
+- **Major Feature Removal:** Completely removed the default account mapping system that was causing confusion and reliability issues
+- **Offline-First Implementation:** Implemented robust offline account mirroring system that maintains local copies of all FireFly III accounts
+- **Key Changes:**
+  - **AccountCacheService:** Removed all default account mapping functions (saveDefaultAccount, getDefaultAccount, etc.)
+  - **ReceiptProvider:** Updated to not rely on default account mapping, using direct account selection instead
+  - **TransactionScreen:** Removed default account mapping UI elements and logic
+  - **ConfigScreen:** Removed default account mapping display and management controls
+  - **AccountDialogService:** Updated account selection dialogs to work without default mappings
+  - **ReceiptService:** Removed default account mapping related functions
+  - **LocalReceiptService:** Updated to not depend on default account mappings
+- **New Features:**
+  - Account mirroring system that stores all accounts locally for offline access
+  - Fallback mechanism: server accounts > mirrored accounts > empty list
+  - Automatic account sync when connection is available
+  - Manual sync button in config screen
+- **Benefits:**
+  - Simplified architecture without complex default mapping logic
+  - Better offline reliability - app works completely without server connection
+  - Faster startup times using local account cache
+  - More predictable account selection behavior
+  - Reduced confusion about which accounts are being used
+- **Testing Results:** Application successfully runs in offline mode with mirrored accounts, maintains functionality when server is unavailable
