feat: add privacy settings for time and timezone in context

- Add includeCurrentTime and includeTimezone settings to ProviderSettings
- Update getEnvironmentDetails to respect privacy settings
- Create PrivacySettings UI component with proper controls
- Add timezone dependency on current time setting
- Include comprehensive test coverage for privacy settings
- Add translations for privacy settings UI
- Default to true for backward compatibility

Fixes #8731
