Address Serbian RESET + CodeRabbit comments on PR #50

Serbian (Uncle directive 17:38 UTC following the Spanish fixes):
- translations/serbian.json: 'RESET' was left as English key (flagged
  by validate-packs as Common UI label untranslated). Now 'RESETUJ'.
  Matches sibling locales handling 'RESET' via their own word + the
  Serbian file's imperative style (e.g. 'Restart' -> 'Restartuj').

CodeRabbit actionable comments on PR #50:
- translations/hindi.json:2218: 'Yes' was 'मैं आपकी सहायता कैसे कर सकता/
  सकती हूं?' (LLM assistant prompt 'How can I help you?') - fixed to
  'हाँ' per CR suggestion. Residual contamination from pre-validator
  era that Khush's cleanup missed; good regression case.
- Services/TranslationValidationRules.cs:46-47: German localized-meta
  patterns were the only entries in the array missing
  RegexOptions.IgnoreCase. Added the flag so capitalization variants
  ('Geben Sie...' vs 'geben Sie...') get caught. Matches every other
  language block in the array.
- translations/dutch.json:770: 'Voor een specifiek item van je sjabloon'
  used informal 'je' while the file overwhelmingly uses formal 'u/uw'
  register. Switched to 'uw sjabloon' for consistency.

Verified: dotnet build clean, validate-packs reports 0 issues.
