Lint cleanup: ruff fixes across entire codebase
- Strip trailing whitespace from all Python files - Fix import sorting (I001) across all modules - Convert Optional[X] to X | None syntax (UP045) - Remove unused imports (F401) - Convert lambda assignments to def functions (E731) - Add TYPE_CHECKING import for forward references - Update pyproject.toml ruff config: - Move select/ignore to [tool.ruff.lint] section - Add per-file ignores for DCT colorspace naming (N803/N806) - Add per-file ignores for __init__.py import structure (E402) - Exclude defunct test_routes.py - Remove frontends/web/test_routes.py (defunct debug snippet) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
