Implement hybrid two-tier cache system with full monitoring and Telegram bot enhancements

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
