Bohan Jiang 60c5848794 feat(invitation): dedicated /invite/{id} page for accepting invitations (#1023)
The email CTA now deep-links to /invite/{id} instead of the generic app
URL. If the user isn't logged in, they're redirected to login with a
?next= param that brings them back to the invite page.

Changes:
- Backend: GET /api/invitations/{id} endpoint (enriched with workspace/inviter names)
- Backend: Email template now links to /invite/{invitationId}
- Frontend: Shared InvitePage component (packages/views/invite/)
- Frontend: Web route at (auth)/invite/[id], Desktop route at invite/:id
- Frontend: /invite/ excluded from navigation history persistence
