[HACK] Remove unused resources

[kidinov]

Description

Remove unused color, drawable, dimension, and string resources identified by Android lint. This cleanup reduces the APK size by removing approximately 700+ unused string resources, 30+ color definitions, 20+ dimension values, and 15+ drawable files that are no longer referenced in the codebase.

Changes include:

• Removed 704 unused string resources while preserving comment structure
• Removed 27 unused color definitions from colors_base.xml
• Removed 18 unused dimension definitions from dimens_base.xml
• Removed 13 unused alpha values from alphas.xml
• Deleted 16 unused drawable files across multiple density folders
• Removed 2 unused color selector XML files

Steps to reproduce

1. Build the app using ./gradlew assembleVanillaDebug
2. Verify the app starts and functions normally
3. Check that no resources are missing or broken

Testing information

• While green CI should be enough, scan through the changes to make sure that none of the deleted resources were used in runtime

• I have considered if this change warrants release notes and have added them to RELEASE-NOTES.txt if necessary. Use the "[Internal]" label for non-user-facing changes.
