🔧 refactor: Permission handling for Resource Sharing (#11283)

* 🔧 refactor: permission handling for public sharing

- Updated permission keys from SHARED_GLOBAL to SHARE across various files for consistency.
- Added public access configuration in librechat.example.yaml.
- Adjusted related tests and components to reflect the new permission structure.

* chore: Update default SHARE permission to false

* fix: Update SHARE permissions in tests and implementation

- Added SHARE permission handling for user and admin roles in permissions.spec.ts and permissions.ts.
- Updated expected permissions in tests to reflect new SHARE permission values for various permission types.

* fix: Handle undefined values in PeoplePickerAdminSettings component

- Updated the checked and value props of the Switch component to handle undefined values gracefully by defaulting to false. This ensures consistent behavior when the field value is not set.

- Updated expected permissions in tests to include CREATE permission for various permission types.
