Backend:
- Create notifications table (user_id, workspace_id, type, channel,
title, body, data JSON, read_at, archived_at)
- Create Notification model with Type enum (post_failed,
account_disconnected, invite_received, member_joined, member_removed)
and Channel enum (email, in_app, both)
- Create SendNotification job: isolated from publish flow, handles
saving in-app notification and sending email independently
- NotificationController: index (excludes archived, scoped to workspace),
markAsRead, markAllAsRead, archiveAll
- Integrate with PublishToSocialPlatform (post failed/partial)
- Integrate with VerifyWorkspaceConnections (batch disconnection)
- Integrate with SocialAccount::markAsDisconnected (single disconnection)
- All use SendNotification::dispatch() instead of direct Mail::to()
Frontend:
- NotificationBell component in sidebar footer with unread badge
- Dialog with notification list, mark as read, mark all read, archive all
- Click navigates to relevant page (post edit, accounts)
- i18n for notifications UI (en, es, pt-BR)
Tests:
- 8 tests for NotificationController (auth, CRUD, workspace scoping)
- 4 tests for SendNotification job (channels, email, data storage)
All 745 tests passing.
