frontend: safe fixes from the #109 punch-list

- CallSpineEntry.tsx: drop the dead `hasAudio` prop + the early `return null`
  that sat between hooks in InlinePlayer (React #310 risk). Parent already
  gates the mount on audio presence.
- NodeCard.tsx + nodes/page.tsx: pending-node card no longer double-fires.
  NodeCard gains `linkToDetail` (default true); the pending branch passes
  false so the wrapping onClick (open config modal) isn't swallowed by the
  inner <Link> navigation. List view unchanged.
- trips/page.tsx: TripCard badge now buckets on end_date >= today, matching
  the list's own upcoming/past split — an in-progress trip no longer shows a
  "Past" badge under "Upcoming".
- trips/page.tsx, NodeConfigModal.tsx, nodes/[id]/page.tsx: tall modals get
  `p-4` on the overlay + `max-h-[90vh] overflow-y-auto` on the panel so they
  don't clip on short viewports (incidents' CreateModal pattern).
- lib/types.ts: IncidentRecord.units / vehicles are optional now, matching
  Firestore (older docs omit them); incidents/[id] gains a `?? []` guard.

Untypechecked (no node/npm locally). next build in deploy.yml gates it.
Full list of remaining items in server-26 #109.
