feat(telegram): Unify Trezorerie button (Casa + Banca combined)

- Replace separate [Trezorerie Casa] and [Trezorerie Banca] buttons
  with single unified [Trezorerie] button in main menu
- Add format_treasury_combined_response() formatter showing:
  - Grand total (Sold Trezorerie)
  - Casa section with total + all accounts
  - Banca section with total + all accounts
- Compact menu layout: Row 2 [Sold Companie][Trezorerie],
  Row 3 [Sold Clienti][Sold Furnizori], Row 4 [Evolutie Incasari]
- Use Romanian number format (period as thousands separator)

Also includes:
- Oracle pool: Support both SERVICE_NAME and SID connections
  (ORACLE_SERVICE_NAME takes priority over ORACLE_SID)
