The pre-commit hooks declared `language: system` with bare `ruff`/`ty`
entries, but both are uv-managed dev dependencies and are not on PATH, so every
commit failed with `Executable 'ruff' not found`. Route both through
`uv run`; keep ruff blocking and make ty advisory (verbose) until its 18
whole-project diagnostics are cleared.
With the gate working, clear `ruff check .` to zero:
- 18 auto-fixes (import sorting, blank lines, `max()` simplification,
`with` merging, unused imports).
- Real defects: `SourceNavigation` annotated but never imported in
sources_page; two naive `datetime.now()` calls in migration.py now use
`datetime.now(UTC)`.
- Dead parameters removed: `source_has_photo_table` (computed, passed, never
read), `_serialize_value(key=...)`, and unused `request` on two NiceGUI
page handlers where the framework injects it optionally.
- Mechanical line-length wrapping and one `startswith` tuple collapse.
- `# noqa: PLR0915` / `# noqa: PLR1702` on five long UI/migration
functions, following the convention already used in jobs_page and
settings_page, rather than refactoring during stabilization.
Full suite green (377 tests, `-m "not external"`).
