Develop - Localization and minor fixes!

[sameerasw]

This pull request refactors and improves the FeatureSettingsActivity to enhance maintainability, localization, and feature handling. The most significant changes include switching permission-related UI strings to use string resources for localization, utilizing a feature registry for feature metadata, and improving how feature-specific screens are handled.

Localization and Internationalization:

• All permission sheet UI strings (titles, descriptions, action labels) are now referenced from string resources (R.string.*) instead of hardcoded text, enabling proper localization throughout the permission dialogs. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
• The Android manifest now specifies a localeConfig, further supporting app localization.

Feature Handling Improvements:

• Feature metadata is now fetched from a centralized FeatureRegistry, replacing the previous hardcoded map. This improves maintainability and scalability as new features are added. [1] [2]
• Feature-specific logic now uses the feature ID consistently (featureId) instead of the previous feature variable, reducing errors and improving clarity. [1] [2] [3] [4]

UI/UX Enhancements:

• The "Link actions" feature now launches a dedicated LinkPickerScreen demo when selected, providing a more direct and relevant user experience.

Code Quality and Imports:

• Added missing imports for string resource access and the feature registry. [1] [2]

These changes collectively improve the app's internationalization, code maintainability, and user experience.
