feat: refresh shared Git config mounts live

- Use profile-scoped canonical Git clone sources with locked refreshes
- Mount shared Git configuration read-only and isolate profile content
- Add API and desktop/mobile actions for live Git mount refresh

Quality gates: frontend build and backend py_compile passed.
Skipped: backend pytest/Ruff unavailable; Docker/manual checks not approved.
