Krzysztof kuhy Rudnicki ee27d10fef Reduce per-file-ignores by fixing lint violations across codebase
Fix ruff violations in ~15 source files and ~60+ test files to minimize
per-file-ignores in pyproject.toml. Remaining ignores are justified with
comments explaining why each suppression is necessary.

Source fixes: FBT003 (keyword args), S310 (URL validation), SLF001
(private access), T201 (print→logging), C901 (complexity), E501 (line
length), E402 (import order).

Test fixes: SIM117 (combined with), FBT (boolean args), PERF203 (try in
loop), S310/S607 (URLs/executables), E402/E501 (imports/lines), S108
(tmp paths), PLR0913 (too many args), ARG (unused args), ANN (type
annotations), RUF059 (unused unpacked vars), PT019 (fixture naming).

Remaining per-file-ignores (with justifications):
- Tests: ARG, D, PLC0415, PLR2004, S101, SLF001
- music_gen sources: PLC0415 (heavy ML lazy imports)
- moviepy_showcase: PLC0415 (circular dependency)
- generate_images: PLR0913 (matplotlib helpers need many params)
- praca_magisterska_video: E501, E402 (long paths, mpl.use)
