Bug: English File Error Handling & Test Coverage

[khushal-winner]

Describe the bug

The translation checking system in scripts/check_translations.py has two critical bugs:

1. Silent English file failure: Lines 128-130 silently continue when english_tags is empty, causing corrupted English files to result in CI passing when it should fail
2. Missing extra tags detection: The _check_translation_tags() method never detects translation tags that exist in non-English files but are absent from English reference files

Expected behavior

1. Loud failure: Corrupted/empty English files should cause CI to fail with clear error messages
2. Complete validation: Translation checker should detect and report "extra tags" alongside missing/untranslated/empty tags

Desktop

OS: Windows/Linux/MacOS (affects all)
Browser: N/A (backend system)
Version: All current versions

Additional context

Why we need this fix:
Production impact: Broken English files cause API to serve empty responses → users see "No cards available" instead of security guidance
Detection difficulty: CI always passes due to || echo "Translation issues found, continuing..." workaround

Why we need test coverage:
Current tests: Only test happy paths with valid files, giving false confidence
Missing coverage: No tests for malformed/empty English files, extra tags detection
Regression prevention: Without proper tests, these critical bugs will reoccur

@khushal-winner the extra tags points somehow it look real But I checked the file and couldn't find the CI part you mentioned.
