feat(hints): scale coverage — 11 new registry entries + inject across pages

Registry grows from 14 → 25 hints. New entries:
- wo.dashboard.topbar_actions / meta / tabs / history / finance /
  timeline / bottom
- wo.create.overview
- crm.clients.overview / vehicles.overview
- finante.dashboard.stats / expenses.overview

"?" icons injected into:
- WO dashboard: top-bar actions, meta header, tabs bar, history card,
  finance card, timeline card, bottom action bar (in addition to the
  existing dashboard title, PDF preview, chat)
- CalendarBoard: title
- PipelineBoard: title
- Excel import wizard: step 1
- Main tenant dashboard (via PanelsRenderHook::PAGE_START scoped to
  Dashboard::class): small banner with a "?" and a shortcut to the
  FAQ page for users who don't see the icons

Users now see hint icons on the primary daily-use screens; more can
be added by dropping <x-hint key="..." /> anywhere.
