Harden recurring cron, bulk delete, error handling; fix semgrep CI

Continued fixes from the multi-agent review:

- recurring tickets cron: now that the parse error is fixed the job runs,
  exposing two latent bugs. (1) next_run_at was only advanced after the
  full success path, so any failure (e.g. a NULL created_by passed to the
  non-nullable assignTicket() $assignedBy -> TypeError) left it in the past
  and re-created a duplicate ticket every cron cycle. Added an atomic
  claimForRun() (conditional UPDATE gated on still-due) called BEFORE
  creation, which also prevents overlapping runs from double-creating.
  (2) The cron used a raw mysqli with no utf8mb4, corrupting non-ASCII
  content; it now uses Database::getConnection(). Also guard the assignment
  so created_by NULL falls back to the assignee.
- bulk delete: attachment files were unlinked inside the DB transaction, so
  an atomic-mode rollback restored rows but the files were already gone.
  deleteTicket() can now defer file removal to the caller, and
  BulkOperationsModel deletes files only after a successful commit.
- UserModel: back-tick the `groups` column (reserved word on MySQL 8.0.2+).
- create_ticket_api.php: stop leaking raw DB/exception messages to callers;
  log server-side and return a generic error. (Also includes a pre-existing
  working-tree tweak that adds title to the manual-ticket dedupe hash.)
- CI: semgrep install failed under PEP 668; add --break-system-packages.
