Walkthrough

Adds an environment-controlled shared upload toggle flag, exposes it through /settings, and updates frontend ingestion controls so shared upload visibility is independent from advanced ingest settings.

Changes

Shared upload toggle

Layer / File(s)	Summary
Backend flag and settings contract src/config/settings.py, src/api/settings/..., tests/unit/config/test_show_shared_upload_toggle.py	Adds and tests OPENRAG_SHOW_SHARED_UPLOAD_TOGGLE, then returns it as show_shared_upload_toggle in SettingsResponse.
Frontend ingestion control contract frontend/app/api/queries/useGetSettingsQuery.ts, frontend/components/cloud-picker/ingest-settings.tsx	Adds the settings field and conditionally renders advanced ingestion controls through the new showAdvancedSettings prop.
Shared bucket integration frontend/components/connectors/shared-bucket-view.tsx	Derives shared-toggle visibility, gates the sync payload, and renders shared-only ingestion settings when enabled.
