fix: scrip engine condition matching and ticket GET endpoint

- engine.ts: remove transaction_type-based scrip filtering. Now uses condition evaluator
  exclusively (matching by scrip.condition_type against transaction types was incorrect —
  'OnResolve' ≠ 'StatusChange'). All non-disabled, queue-matching scrips are evaluated.
- tickets.ts: fix GET /:id — replace broken Drizzle 'with' relation with manual CF join.
  Set up Drizzle relations needed for proper schema typing (customFieldValues → customFields).
