- Add GET /boards/{board_id}/statuses endpoint — direct board-to-statuses lookup
without ticket roundabout; used by filter bar and new ticket form
- Fix TicketsPage and NewTicketModal to call getBoardStatuses(board_id) instead
of misusing getTicketStatuses(ticket_id) with a board_id value
- Fix list_members auth: was require_account_owner (owner/super_admin only) —
changed to require_engineer_or_admin so engineers can see member list for
ticket assignment
- list_members: return [] on PSAError instead of 502 (Lesson 111 pattern)
- get_ticket_statuses: return [] on PSAError instead of 502
