Fix double-firing event handlers, non-bubbling keyboard status event, and saved filter status type

- Remove duplicate edit-comment/delete-comment cases from TicketView.php inline
  script — ticket.js already handles them. Double-call of editComment() would
  immediately open then close the edit form (second call sees .editing → cancels)
- Fix keyboard shortcut 1-4 status change: dispatchEvent(new Event('change'))
  was non-bubbling (default), so the document-level change delegation in TicketView
  never received it. Now uses { bubbles: true } so updateTicketStatus() fires correctly
- Fix saved filter status type: getCurrentFilterCriteria() was saving status as a
  joined string "Open,Pending" but pill-click handler called .join() expecting an array
  (TypeError swallowed by try/catch → status filter silently not applied). Now saves
  as array; applySavedFilterCriteria handles both arrays and legacy strings
- Pill-click handler also updated to handle both array and string status formats
