feat: Add per-workspace codebase indexing control

- Add workspace-specific storage support to ContextProxy
- Update CodeIndexConfigManager to check workspace settings before global
- Add message handlers for workspace-specific indexing settings
- Add UI support with workspace override toggle in CodeIndexPopover
- Add translation keys for new UI elements
- Update tests to support new workspace-specific methods

Fixes #7511
