fix(05-06): add Collection and Remittance CASL subjects, update routes

- Add Collection and Remittance to AppSubjects union type
- Grant OFFICE_STAFF manage:Collection and manage:Remittance
- Grant COLLECTOR create/read:Collection and create/read:Remittance
- Update all 8 collection/remittance route handlers from Subscriber to
  their dedicated CASL subjects (Collection or Remittance)
- Update JSDoc comments in route files to reflect new subject names
