Implements VAT (TVA) balance tracking for both previous and current month with
mutually exclusive calculations (either payable OR recoverable per period).
Backend Changes:
- Add 4 TVA fields to DashboardSummary model
- Implement TVA query from vbal table (accounts 4423, 4424, 4426, 4427)
- Add exclusive calculation logic:
* Previous month: difference between account 4423 (payable) OR 4424 (recoverable)
* Current month: difference 4427-4426 (payable if >0, recoverable if <0)
Telegram Bot Changes:
- Add compact TVA section to dashboard formatter
- Display only when values > 0
- Format: "TVA de plată/recuperat precedent/curent"
Example output:
**Solduri TVA:**
- TVA de plată precedent: 7,284 RON
- TVA de recuperat curent: 3,200 RON

Cache System (Backend):
- Implemented two-tier hybrid cache: L1 (in-memory) + L2 (SQLite)
- L1 cache: Fast dictionary-based with 5-minute TTL for hot data
- L2 cache: Persistent SQLite with 1-hour TTL for warm data
- Cache decorator with automatic tier management and fallback
- Cache key generation with per-user isolation
- Event monitoring system for cache statistics
- Cache benchmarking utilities for performance testing
- Added cache management endpoints: /api/cache/stats, /api/cache/clear, /api/cache/benchmark
- Cache configuration via environment variables (CACHE_ENABLED, CACHE_L1_TTL, etc.)
Backend Services:
- Updated dashboard_service to use @cached decorator with request context
- Added cache support to invoice_service and treasury_service
- Integrated cache manager into main.py with lifespan events
- Added Request parameter to service methods for cache metadata
Frontend Enhancements:
- New CacheStatsView.vue for real-time cache monitoring dashboard
- Cache store (cacheStore.js) for state management
- Updated router to include /cache-stats route
- Navigation updates in DashboardHeader and HamburgerMenu
- Cache stats accessible from main navigation
Telegram Bot Improvements:
- Enhanced formatters with YTD comparison data
- Improved menu navigation and button layout
- Better error handling and user feedback
- Bot startup improvements with graceful shutdown
Auth & Middleware:
- Enhanced middleware with cache metadata injection
- Improved request state handling for cache source tracking
Development:
- Updated start-dev.sh with better error handling
- Added TELEGRAM_EMAIL_AUTH_PLAN.md documentation
- Updated requirements.txt with aiosqlite for async SQLite
Performance:
- L1 cache provides <1ms response for hot data
- L2 cache provides ~5ms response for warm data
- Database queries only for cold data or cache misses
- Cache hit rates tracked and displayed in real-time
