Repair the pre-commit quality gate and clear the ruff backlog

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"`).

+"""Deterministic orphan sweep for the `transcription` package.
+
+`.github/skills/python-code-reviewer/skill.md` requires every review to report
+orphaned code as removed, retained-with-justification, or uncertain-follow-up. This
+guard makes that sweep reproducible: it locks the current set of unreferenced public
+definitions, so a newly stranded function fails the build instead of accumulating
+silently, and deleting a known orphan requires deleting its entry here.
+
+The sweep is intentionally conservative. It only considers module-level public
+definitions, and it honours the dynamic-wiring exceptions the skill calls out:
+framework route registration, string-based entrypoint references, and use from
+`tests/` or `tools/`.
