fix: sync SubmitActionOptions type with backend submit_action endpoint (#1704)

## Summary
- Synced `SubmitActionOptions` type with the backend
`SubmitActionRequest` struct from the chat repo
- Added 13 missing action payloads: `block`, `custom`,
`delete_activity`, `delete_comment`, `delete_reaction`, `end_call`,
`escalate`, `flag`, `kick_user`, `mark_reviewed`, `reject_appeal`,
`shadow_block`, `unblock`
- Added missing fields on existing payloads (`ban`, `delete_message`,
`delete_user`, `restore`, `unban`)
- Added top-level `appeal_id` field

## Linear ticket

https://linear.app/stream/issue/MOD2-708/update-chat-js-sdk-to-support-the-updated-types-in-submit-action

## Test plan
- [x] TypeScript compiles cleanly (`tsc --noEmit`)
- [ ] Verify no downstream consumers break with the expanded type
