feat(5.9): US-005 - poll-guard modal/bife pe trigger periodic

- base.html: listener htmx:beforeRequest scopat la #submissions-wrap care
  anuleaza (preventDefault) DOAR poll-ul periodic (fara requestConfig.triggeringEvent)
  cat timp modalul de detaliu e deschis SAU exista checkbox de bulk bifat.
- F5/R6: trimiteriChanged si submit-ul de filtru au triggeringEvent -> trec mereu,
  deci pauza nu ramane lipita permanent daca randul bifat paraseste filtrul.
- Resume automat (anularea nu opreste timer-ul htmx) + resume explicit pe checkbox
  change via delegare pe body -> trimiteriChanged from:body (pastreaza filtrul).
- Vechea pauza pe „rand expandat" (5.8) era deja inlocuita de modalul global (US-003).
- 3 teste noi in tests/test_web_modal.py; suita 843 passed, 1 deselected.
