build(backend): close the lint gaps the E32 audit measured
ruff gains RUF100, PLW1510 and flake8-bugbear, every hit fixed rather than ignored. B008 stays on with FastAPI's Depends/Query declared immutable. basedpyright moves to standard mode, pytest to --strict-markers, and a hand run of pytest now requires the database unless SIFTLODE_TEST_REQUIRE_DB=0. PLW1510 found a real bug: the three ffprobe probes in plex/stream.py never looked at the exit status, so a probe that failed was read as the file's truth (an HDR source sent down the HW-safe path, a multi-audio file collapsed to one track, a subtitle offset taken from garbage) and the warning each except branch promises never fired. They now run with check=True.
