Consolidate models and tests into single files, extract database utilities

[Copilot]

Refactored Django models and tests from multiple individual files into consolidated single files for improved maintainability and discoverability. Database utilities extracted into a dedicated package.

Changes

Models consolidation

• Merged 11 separate model files into simplecasts/models.py (808 lines)
  • Combined: users.py, categories.py, podcasts.py, episodes.py, subscriptions.py, bookmarks.py, audio_logs.py, recommendations.py
  • Preserved all model classes, QuerySets, and Season dataclass
  • Resolved import dependencies by ordering classes appropriately
  • Converted from package (models/__init__.py) to single file (models.py)

Tests consolidation

• Merged 8 test files into simplecasts/tests/test_models.py (563 lines)
  • Consolidated all model and manager test classes
  • Maintained test organization with section comments
  • Renamed from models.py to test_models.py to follow pytest conventions

Database utilities package (new)

• Created simplecasts/db/ package for reusable database utilities
  • db/fields.py - Contains URLField with sensible defaults
  • db/search.py - Contains SearchQuerySetMixin for full-text search
  • db/validators.py - Contains url_validator (moved from root)
• Removed __all__ from models module for cleaner exports

Import updates

• Updated admin.py to import QuerySets from consolidated models module
• Models now import database utilities from simplecasts.db
• Updated all references to validators to use new simplecasts.db.validators location
• All existing from simplecasts.models import ... statements remain compatible

Import compatibility

# All existing imports continue to work unchanged
from simplecasts.models import (
    AudioLog, Bookmark, Category, Episode, Podcast,
    PodcastQuerySet, EpisodeQuerySet,
    Recommendation, Season, Subscription, User,
)

# Database utilities available from new package
from simplecasts.db import URLField, SearchQuerySetMixin, url_validator
