feat(04-01): rewrite /api/mobile/tickets with cursor pagination and exported interfaces
- Replace page/offset pagination with opaque base64 cursor (last_activity_date, id)
- Export MobileTicket and MobileTicketListResponse interfaces for Plan 02 import
- Add requireAuth() gate (T-04-03: legacy route lacked auth)
- Server-side limit cap at 25 rows (D-11, T-04-04)
- Default status filter [1,8,7] when no status param supplied (matches legacy t.status != 5)
- Preserve getMobileCompanyFilter() helper verbatim
- Support status/priority arrays, queue, mine, and search filters
- Cursor seek predicate: (last_activity_date, id) < (cursor) for stable keyset order
