feat: add ?lang=en support to API with default ru

Browse Source 
Language Support:
- Create GetLanguage() helper function
- Support both 'lang' and 'language' query parameters
- Convert short codes (en/ru) to TMDB format (en-US/ru-RU)
- Default language: ru-RU

Changes:
- pkg/handlers/lang_helper.go: new helper for language detection
- pkg/handlers/movie.go: use GetLanguage() in all endpoints
- pkg/handlers/tv.go: use GetLanguage() in all endpoints

How to use:
- ?lang=en → returns English content
- ?lang=ru → returns Russian content (default)
- No param → defaults to Russian

All movie/TV endpoints now support multilingual content:
GET /api/v1/movies/{id}?lang=en
GET /api/v1/movies/popular?lang=en
GET /api/v1/tv/{id}?lang=en
etc.
