fix: improve API response parsing with detailed logging

Problem:
- Gray screens on movie details and downloads
- No error messages shown to debug issues
- API response structure not fully validated

Solution:

1. Enhanced Movie.fromJson() parsing:
   - Added detailed logging for each parsing step
   - Safe genre parsing: handles [{id: 18, name: Drama}]
   - Safe date parsing with null checks
   - Safe runtime parsing for both movies and TV shows
   - Better media type detection (movie vs tv)
   - Comprehensive error logging with stack traces

2. Added detailed API logging:
   - getMovieById(): Log request URL, response status, body preview
   - getTvShowById(): Log request URL, response status, body preview
   - Log API response structure (keys, types, unwrapped data)
   - Makes debugging much easier

3. Based on backend API structure:
   Backend returns: {"success": true, "data": {...}}
   Movie fields from TMDB:
   - id (number)
   - title or name (string)
   - genres: [{"id": int, "name": string}]
   - release_date or first_air_date (string)
   - vote_average (number)
   - runtime or episode_run_time (number/array)
   - number_of_seasons, number_of_episodes (int, optional)

Logging examples:
- 'Parsing Movie from JSON: [id, title, genres, ...]'
- 'Parsed genres: [Drama, Thriller, Mystery]'
- 'Successfully parsed movie: Fight Club'
- 'Response status: 200'
- 'Movie data keys: [id, title, overview, ...]'

Changes:
- lib/data/models/movie.dart: Complete rewrite with safe parsing
- lib/data/api/neomovies_api_client.dart: Add detailed logging

Result:
✅ Safer JSON parsing with null checks
✅ Detailed error logging for debugging
✅ Handles all edge cases from API
✅ Easy to debug gray screen issues via logs

Next steps:
Test the app and check Flutter debug console for:
- API request URLs
- Response bodies
- Parsing errors (if any)
- Successful movie loading messages
