Documentation Sub-Issue: Synchronize String Resources Across All Languages

[arn-c0de]

Ensure that all language string resources are always complete and fully aligned with the default English strings (values/strings.xml).
All supported languages must:

• Contain exactly the same string keys
• Stay in sync with any newly added or modified strings
• Never fall back to English due to missing entries

Source of Truth

File: app/src/main/res/values/strings.xml (English / Default)

All other language files must be kept in sync with this file.

Automated String Detection Tool

A tool for detecting missing and inconsistent strings is now available in the repository:

• Location: scripts/TranslationStringTools/
• Reports Output: scripts/TranslationStringTools/reports/

The tool automatically compares all language files against the English source and generates reports showing:

• Missing string keys per language
• Coverage percentages
• Outdated / potentially incorrect translations
• Unused or obsolete keys

Language Status Tracking

Every language must be kept complete and up to date.

Legend:

• ✅ = folder exists and is (nearly) complete
• ⬜ = not yet added / incomplete / needs review

Tasks

Repository Status Check

• Audit all app/src/main/res/values* folders
• Document which language folders already exist
• Identify languages that need to be created from scratch

String Consistency

Compare every values-XX/strings.xml against values/strings.xml:

• Detect missing keys
• Identify outdated translations
• Find unused / obsolete keys

Codebase Audit

• Remove all hardcoded UI strings
• Ensure every piece of UI text uses string resources

Process Definition

Rule:
Every new or modified string must be added / updated in all languages.
Missing translations must be clearly marked (e.g. with TODO comments or @string/missing_... placeholders).

Automation

• Run the detection tool from scripts/TranslationStringTools/ regularly
• Review generated reports in scripts/TranslationStringTools/reports/
• Optional: Add CI check / warning for translations below 100% coverage

Definition of Done

• All language files contain all string keys from the default English file
• No silent fallbacks to English due to missing resources
• The update process is documented and actively enforced
• The detection tool reports 100% coverage for all active languages
