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)
