refactor(settings): update settings UI for FileSource configuration

- Refactor FileSourceSettings component for dynamic configuration
- Update IndexSettingsTab with improved worker processing controls
- Update setting definitions to support new FileSource structure
- Add settings migration for FileSource configuration changes
- Remove legacy excludePatterns in favor of unified filter rules
