feat: Phase 10b — Self-service UI (group create/join, upload, IndexedDB, search)

Six self-service features for the web SPA:
- Group creation UI with GEK auto-generation (AES-256-GCM ECIES)
- Member management + invite by username (GEK wrapping for invitee)
- Open group self-join flow (POST /v1/groups/{id}/join)
- File upload client→node (FILE_UPLOAD MNP type, .uploads/ staging)
- IndexedDB caching of group file indexes (instant display on revisit)
- Cross-group file search (SearchPage, pure client-side on cached indexes)

11 new tests (166 total): 8 group self-service + 3 AES GEK wrap/unwrap.
