Refactor settings management to use SettingsDefaultsManager

Browse Source 
- Introduced SettingsDefaultsManager to centralize default settings and loading logic.
- Updated context-generator, SDKAgent, SettingsRoutes, and worker-utils to utilize the new manager for loading settings.
- Removed redundant code for reading settings from files and environment variables.
- Ensured fallback to default values when settings file is missing or invalid.
