refactor(routers): comment out legacy endpoints across multiple routers

Disabled legacy routes that are superseded by V3 equivalents. Code is
commented out (not deleted) pending final verification and cleanup pass.

- registry.py: remove sql, lookup (/lu), websockets, websockets_redis;
  clean up dead imports (contact, event_person, etc.)
- data_store.py: comment out legacy CRUD and code-lookup endpoints;
  keep V3 code-lookup routes active; add TODO for action path rename
- api.py: comment out Api_Base CRUD, get_id (internal ID leak),
  and sql_test (debug) endpoints
- aether_cfg.py: comment out legacy Flask cfg endpoint
- user.py: comment out legacy user endpoints
- util_email.py: minor cleanup
