frontend: label machine-generated output and unbuilt entitlements (Gate A)

Gate A (BUSINESS_MODEL.md, board minutes #42, dated to today by minutes #79
decision 14) blocks putting a price or an unbuilt entitlement claim on a
surface a reader can see, and requires that unverified machine assertions be
labelled as such on the same screen as the assertion.

The pricing leg was already met — /pricing and both homepage CTAs stopped
quoting the invented catalog. Condition A2 was not: a search of the whole
frontend for a "machine-generated" or "unverified" qualifier returned zero
hits. Every transcript, summary, title, location, unit list and vehicle list
is pipeline output that no human reviews, and entity-name accuracy in those
transcripts has never been measured (server-26#48) — yet all of it was
rendered to the reader as plain fact. Unqualified machine assertions about
real incidents and real people is the exposure Gate A exists to stop.

A2 — one reusable element, components/ui/MachineOutputNotice.tsx, rendered on
the same screen as the output (a footnote elsewhere does not satisfy A1's
"same screen" standard). Three variants for three shapes of surface, all
saying the same thing; the "popup" variant uses fixed grays because a Leaflet
popup is stock-white in both themes. Covered:

  - incident detail: under the summary (covers summary, title, location,
    units on scene/cleared, vehicles, tags) and above the call spine
  - incident list: above the timeline groups
  - Archive (/calls): above the transcript rows
  - node detail: above the Recent Calls table
  - Watch//alerts: above the events table, whose Snippet column is transcript
    text and whose keyword match was made against it
  - Live map: the desktop incident rail, pinned above the scroll area so it
    cannot be scrolled off the screen it qualifies; the mobile drawer; the
    incident marker popup; the incident-path stop popup
  - /systems: the source-call transcript preview
  - /features: the two marketing sections that describe the AI pipeline

A1 — components/ui/UnbuiltMarker.tsx marks a claim unbuilt inline:

  - /faq: the retention answer promised 7/90/365-day windows. There is no TTL
    and no deletion sweep anywhere in the product (server-26#44), so the
    answer now states plainly that nothing is deleted automatically and marks
    per-plan retention as not yet available.
  - /settings/billing: the plan cards' claims — custom retention, SSO/SAML,
    uptime SLA, data residency — are marked not-yet-available next to the plan
    that makes them.

Labelling only. No retention, SSO, SLA or residency was built; no billing,
Stripe or checkout code was touched (Gate B still bars charging anyone); no
price was added anywhere; no Python was touched. Both themes verified against
the light-mode !important overrides in globals.css, which are untouched.

tsc --noEmit clean.
