ChuckBuildsandClaude Sonnet 5 23dcdc2d49 test(web): smoke tests + static-analysis audits for the web UI
Guardrails so this branch's fix classes can't regress silently:

- test_web_smoke.py (24 tests): boots the pages blueprint with the same
  dual registration app.py uses and asserts every page/partial returns 200
  with its load-bearing markers (nav wiring, getting-started card, advanced
  section, rotation order card, per-mode duration inputs), the /v3 legacy
  alias serves everything, all critical static assets (incl. vendored
  fontawesome/codemirror, PWA manifest/icons) are served, durations group
  per plugin with the leftover bucket, and the advanced-hardware section
  really contains the tuning fields. Would have caught this session's
  unreachable-durations-page and orphaned-tab bugs instantly.
- test_web_static_audit.py (3 tests): (1) every responsive utility class
  referenced in templates is actually defined in app.css - the
  silently-no-op class bug that left the header search box invisible at
  every width; (2) every url_for('static', ...) reference points to a real
  file; (3) any JS file calling the debugLog global declares it in a
  /* global */ header.

All 40 web tests pass (24 + 3 new, 13 existing) under pytest + Flask.

"""
Static-analysis audits for the web UI, as tests so CI enforces them.
1. Breakpoint utility audit: app.css hand-maintains a Tailwind-style utility
subset, so a template can reference a responsive class (e.g. sm:block)
that no CSS rule defines — it silently no-ops. This once left the header
search box and system stats invisible at every screen width. The audit
diffs classes used in templates against classes defined in app.css.
2. Asset reference audit: every url_for('static', filename=...) in the
templates must point to a file that exists, so a renamed/moved asset
can't ship as a broken <script>/<link>/<img>.
3. debugLog globals audit: any static JS file calling debugLog() (a global
defined in base.html) must declare it in a /* global */ header so linting
stays clean and the dependency is explicit.
