merge(dev): reconcile photo editor security and upstream changes

- Reconcile conflict resolution in routes/editor_agent_routes.py and src/editor_agent_model.py
- Enforce strict server-authorized endpoint resolution and reject client URL overrides
- Enforce bearer-token privilege separation: delegated API tokens are capped at non-admin scope per src/tool_security.py and cannot inspect private base URLs or probe metadata
- Preserve chat-scope authorization, missing-session 401 rejection, and owner-scoped browser bridge/SSE queues
- Preserve administrator-disabled-tool denylist enforcement introduced by PR #6357
- Fix mobile toolbar flyout hit-testing and stacking context trapping on viewports <= 700px via scoped elevation and mask suppression
- Stabilize project recovery test fixture by awaiting document draft quiescence prior to baseline capture
