Align python-code-reviewer skill with repo ground truth

Update the reviewer skill so its procedure matches how this repo actually works:

- Route review reports to docs/reviews/ and mark them non-canonical, resolving the conflict where reports landed in the same docs/ tree they resolve findings against.
- Pin verification commands to uv (uv run ruff check / ty check / pytest -m 'not external').
- Record the pytest contract: strict markers, strict asyncio mode, and the never-awaited-coroutine warning promoted to an error.
- Convert the deterministic checks to a table with an Enforced by column; three checks are unenforced and one only partial, which are now findings by construction.
- Add a consequence-based severity rubric and a Direction column for bidirectional drift.
- Escalate test-suite concerns to test-effectiveness-auditor.

Also fix tests/test_db.py, which was missing 'from sqlalchemy import text' while using it in 14 places. Three tests were failing with NameError. Wrapped the pre-existing long lines in the same file so it lints clean.

Document the deliberate nicegui==3.13.0 pin in pyproject.toml, a new runbook dependency upgrade policy, and the reviewer skill, so the pin is not flagged as a defect or widened as incidental cleanup.

+## 6. Dependency upgrade policy

+Dependencies are declared in `pyproject.toml` and resolved through the committed

+control what a deliberate `uv lock --upgrade` is allowed to move.
+
+### NiceGUI is pinned exactly (`nicegui==3.13.0`)
+
+1. **Rationale.** NiceGUI bundles Quasar and Vue. Minor releases change component
+   props, slots, and styling, which surfaces as visual and interaction regressions
+   rather than import or type errors. The UI suite under `tests/ui/` asserts
+   structure and behavior, not rendered appearance, so a NiceGUI bump can pass the
+   full test suite and still degrade the interface.
+2. **Scope of risk.** All NiceGUI usage is confined to `src/transcription/ui/` and
+   uses only the public `nicegui.ui` and `nicegui.events` surfaces. The coupling is
+   shallow, so the pin is about release stability, not about unpicking deep
+   framework entanglement.
+3. **Current stance.** Hold the exact pin through release stabilization. Do not
+   widen it as incidental cleanup, and do not let automated dependency updates move
+   it. This includes forgoing patch releases, which is the accepted cost.
+4. **Revisiting.** Treat a NiceGUI upgrade as scheduled work with its own change
+   window: bump the pin deliberately, run `uv run pytest -m "not external"`, then
+   manually verify each page contract in `docs/ui/pages/` before accepting.
+
+### All other dependencies
+
+Declared with `>=` floors and moved by explicit `uv lock --upgrade`. Verify with
+`uv run ruff check .`, `uv run ty check`, and `uv run pytest -q -m "not external"`
+before committing a changed lockfile.
