refactor: address PR feedback for security and cleanups

- refactor: migrate dangerouslySetInnerHTML(t.raw) to t.rich() to prevent HTML injection vectors
- fix: restore per-status wording for flow activation toasts ("Flow activated.", "Archived.", "Saved as draft.")
- chore: remove unused `tComposer` in message-thread.tsx
- chore: remove unused `ROLE_DESCRIPTIONS` in invite-member-dialog.tsx
