Fahim facc50cb0f fix(api): attribute bearer-token actions to the token owner on owner-scoped routes (#4054)
* fix(api): attribute bearer-token actions to the token owner on owner-scoped routes

Owner-scoped chat, session, and upload routes called
get_current_user(), which resolves a bearer ody_ API token to the
sandboxed "api" pseudo-user. A paired API-token client (companion, CLI,
IDE extension) therefore saw and created a separate "api"-owned silo
instead of the owner's data.

effective_user() already exists for exactly this: it attributes a token's
actions to request.state.api_token_owner, is identical to
get_current_user() for cookie sessions, and falls back safely when a
token has no owner. session_routes.py was already migrated; this
completes the migration for the remaining owner-scoped routes:

- chat_helpers.py: chat-privilege enforcement, message attribution, prefs/context
- chat_routes.py: orphaned-endpoint owner, session-auth owner, message search
- upload_routes.py: upload owner attribution + access checks

The /api/models swap is intentionally omitted: #4292 already migrated it
to effective_user (plus the chat-scope gate and ownerless-token 403), so
this PR keeps dev's version of routes/model_routes.py unchanged.

chat_routes.py keeps importing get_current_user for the workspace owner
gate; session_routes.py drops the now-unused import.

* test: target effective_user in auth monkeypatches and owner-scope assertion

The owner-scoped routes now call effective_user() instead of
get_current_user(), so the tests that stubbed get_current_user (or
asserted on it) follow suit:

- test_chat_helpers.py, test_review_regressions.py,
  test_kv_cache_invalidation_2927.py: monkeypatch effective_user
- test_session_endpoint_owner_scope.py: assert the owner-scope guard uses
  effective_user(request)
