Verify M2/M3 implementation, fix regressions against M0/M1

Regressions fixed:
- gateway/src/worker.rs: missing session_manager field in AuthState (M3 regression)
- gateway/src/main.rs: same missing field in monolithic gateway
- storage/src/handlers.rs: removed unused validate_role (now handled by RlsTransaction)

M2 Storage Pillar — verified complete:
- StorageBackend trait with full API (put/get/delete/copy/head/list/multipart)
- AwsS3Backend implementation with streaming get_object
- StorageMode enum (Cloud/SelfHosted) in Config
- All routes: CRUD buckets, CRUD objects, copy, move, sign, public URL, health
- Bucket constraints: file_size_limit + allowed_mime_types enforced on upload
- TUS resumable uploads with S3 multipart (5MB chunking)
- Image transforms run via spawn_blocking
- docker-compose.pillar-storage.yml, templates/storage-node.yaml
- Shared Docker network on all pillar compose files

M3 Auth Completeness — verified complete:
- POST /logout revokes refresh tokens + Redis sessions
- GET /settings returns provider availability
- POST /magiclink with hashed token storage
- DELETE /user soft-delete with token revocation
- Recovery flow accepts new password
- Email change requires re-verification via token
- OAuth callback redirects with fragment tokens
- MFA verify returns aal2 JWT with amr claims
- MFA challenge validates factor ownership
- SessionManager wired into login/logout
- GET /sessions returns active sessions
- Configurable ACCESS_TOKEN_LIFETIME
- Claims model extended with session_id, aal, amr
