CARD + AUTOBANK transplanted from SHOPV3 into SHOPV3_v2.

CARD provider protocol now matches SHOPV3:
- https://naptaikhoan.com/chargingws/v2
- charging/check signature: md5(partner_key + card_code + card_serial)
- status 1 = success; status 2 = cancelled
- credited amount = declared value - configured card fee
- callback and polling/recheck use the same V3 protocol

AUTOBANK:
- BankDepositService in V3 and V3_v2 was already identical, so no downgrade was needed.
- V3 GET cron routes restored:
  /schedule/deposit/{PRJ_KEY}/auto-bank
  /schedule/deposit/{PRJ_KEY}/auto-card
  /schedule/{PRJ_KEY}/run-all
- V3_v2 outbound URL validation/SSRF protection remains intact.
- Existing protected internal cron endpoints remain available with cron.internal.* route names.

No database credentials or .env values were replaced.
