[P0] Fix plugin Base controller to extend ShopXO Common class:
- Now extends Common instead of standalone class
- Automatically gets IsLogin() + IsPower() + ViewInit()
- All child controllers (SeatTemplate/Ticket/Verifier/Verification) inherit fix
[P1] Fix code bugs found during codebase analysis:
- Verifier.php: column('nickname|username', 'id') → CONCAT SQL (syntax error)
- SeatTemplate.php: countSeats() wrong logic (count × rows → per-row scan)
- Ticket.php: verify() returned view on POST → always JSON
- Ticket.php: detail() returned view on error → JSON
- SeatTemplate.php: delete() returned view on POST → JSON, plus soft-delete
[P1] Fix verifyTicket() in TicketService:
- Wrap in Db::transaction() for atomicity
- Add SELECT ... FOR UPDATE pessimistic lock to prevent double-verify
- Add try/catch with error logging
[P2] Fix export() memory issue:
- Replace select() with cursor() to avoid OOM on large datasets
Also: update plan.md with Round 2 findings, claim Task B1/B2/B3/B5
