feat(passenger): show what I reported and how it ended

[catomean]

What was missing

#44 got the crew's answer to the passenger — but only as a four-second toast. Look away, or have the phone asleep when the crew presses Gefunden, and there was no way to find out afterwards: the answer sat in the handover and the passenger app never showed it.

What changed

• components/passenger/MyReports.tsx (new) — "Meine Verlustmeldungen" in the Reisen tab, under the trips: what was reported, where, when, the status badge (from NOTIFICATION_STATUS_CONFIG, the same SSOT the crew cards use), and the crew's note when they left one. "Unter Sitz 42 gefunden, liegt beim Zugpersonal" is worth more to a passenger than the word "Gefunden".
• It reads the same handover the toast reads — no second copy of the answer — and updates live: an answer landing in the crew tab flips the badge without a reload.
• Nothing renders before the first report. An empty box explaining its own emptiness has no business on a screen opened to see trips.
• lib/hooks/useDemoReports.ts (new) holds the read, so the component stays render-only and the storage subscription isn't duplicated per consumer. It starts empty and fills after mount — localStorage doesn't exist on the server, and reading during render would make the first paint disagree with the HTML Next sent.
• Three strings added to lib/labels.ts; no new literals in components.

Verification

npm run verify green: prettier clean, tsc clean, lint 0 errors (22 pre-existing warnings), 71 tests pass, tenant SSOT ok.

Browser against the dev server with no backend: reported "Kopfhörer, weiss, in Ladecase", saw it listed as Neu, answered Gefunden with a note from /staff in a second tab, watched the badge and note appear without a reload — then reloaded / and the record was still there, which is the whole point.

No new tests: the status-badge lookup is already proven exhaustive by the compiler (NOTIFICATION_STATUS_CONFIG[report.status] fails to typecheck if a status is unmapped), and the rest is render-and-subscribe plumbing covered by the browser pass.
