feat: Add per-participant conversation archive (#361) (#362)

* feat: Add per-participant conversation archive (#361)

Adds a Mail-style archive primitive at the participation level, so a single
recipient can hide a conversation from their inbox without affecting the
other participants. New messages auto-unarchive the recipient (configurable).

Closes #361

* style: Fix Pint alignment in createCustomNotifications

* refactor: Address review feedback on archive feature

- Re-lead the participation_archived_index on (messageable_id,
  messageable_type, archived_at) so the inbox listing query in
  Conversation::getConversationsList can actually use it.
- Move auto-unarchive to a single SQL update that reads from the DB
  instead of iterating the (possibly stale) in-memory participants
  collection. Handles null participation_id (system messages) by
  unarchiving all participants in that case.
- Strengthen the idempotency test to assert updated_at also stays
  unchanged on a no-op re-archive, instead of comparing only
  second-resolution archived_at strings.

feat: Add message type filtering for conversation messages (#280) (#359)

Add ofType() fluent method to ConversationService for filtering messages
by type (e.g., text, image, attachment) when retrieving them from a
conversation. Works with both standard and cursor-based pagination.

fix: Pass sorting option through to conversation list queries (#357)

The sorting parameter from the Paginates trait was not being passed
to conversation list queries, resulting in hardcoded DESC ordering.

Closes #301

Fix security issues, bugs, and code quality improvements (#354)

* Fix security issues, bugs, and code quality improvements

- Fix authorize() method name in all FormRequest classes (was `authorized()`
  which Laravel never calls, so authorization was silently skipped)
- Add participant_type validation in BaseRequest to prevent arbitrary class
  instantiation via polymorphic model injection
- Add configurable participant_models whitelist in config
- Fix MessageNotification::markAsRead() which called both update() and save()
  redundantly (update() silently failed due to mass assignment protection)
- Fix createCustomNotifications() inserting empty array when participants
  count is exact multiple of 1000, and off-by-one in chunk threshold
- Replace deprecated $dates property with $casts in MessageNotification
- Fix loose comparison (== to ===) in MessageService::send()
- Remove obsolete .travis.yml (GitHub Actions is the active CI)

* Add tests for validateParticipantType security validation

Covers whitelist enforcement, non-model rejection, nonexistent class
