Helper V2 complete + enrichment worker fixes

Helper system phases 2-7:
- Setup Progress: onboarding checklist with progress ring, auto-detection
  via /status, /api/settings, /api/library, /api/watchlist, /api/automations
- Quick Actions: accent pill buttons in popovers (service cards get
  "Open Settings" and "View Docs" actions)
- Keyboard Shortcuts: full-screen overlay with key cap styling, grouped
  by scope (Global, Player, Helper, Forms)
- Search: fuzzy search across 200+ help entries, 11 tours, and shortcuts
  with cross-page navigation via _guessPageFromSelector()
- What's New: version-tagged highlights with "Show me" navigation,
  red badge on ? button for unseen versions, older version cycling
- Troubleshoot: scans dashboard service cards for disconnected/error
  states, shows fix steps with action buttons, "All Clear" when healthy
- Contextual menu: page-aware tour suggestion at top of menu
- Ctrl+K / Cmd+K opens helper search globally
- First-launch welcome tooltip with pulsing ? button
- Redesigned floating button (48px, accent gradient, glass effect)
- Redesigned menu (unified card panel, accent left-stripe on contextual)

Enrichment worker fixes:
- AcoustID: individual recording matches downgraded INFO→DEBUG to reduce
  log noise (14 lines for one track → 1 summary line)
- Name normalization: strip " - Suffix" dash format (Spotify) same as
  "(Suffix)" parens format across all 8 workers. Fixes false mismatch
  on tracks like "Electric Eyes (Studio Brussels Remix)" vs
  "Electric Eyes - Studio Brussels Remix" (was 0.54, now matches)
