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

Implements cache tier identification in Telegram bot to display data source:
- "db" for database queries
- "cached L1" for in-memory cache hits
- "cached L2" for SQLite cache hits
Backend changes:
- Added cache metadata fields to TrendsResponse and DashboardSummary models
(cache_hit, response_time_ms, cache_source)
- Updated /api/dashboard/summary and /api/dashboard/trends endpoints to
include cache metadata when X-Include-Cache-Metadata header is present
- Cache metadata is extracted from request.state (set by @cached decorator)
Telegram bot changes:
- Updated API client to send X-Include-Cache-Metadata header
- Modified helpers to extract cache_source from backend responses
- Updated handlers to pass cache metadata to formatters
- Performance footer now displays specific cache tier (L1 vs L2)
Fixed Pydantic serialization issue:
- Changed field names from _cache_hit to cache_hit (without underscore)
- Pydantic excludes underscore-prefixed fields from JSON by default
