AI disclaimer: one shared component, shown where model output appears

"Freezmo uses AI and can make mistakes. Double-check important info."
(plus a natural informal Czech translation), rendered by a shared
AiDisclaimer so the copy, style and translations live in one place.

Placements — only where the model's words reach the screen:
- Chat: under the composer, below the context/model chips — always (chat
  is pure model output, so it also shows in the empty state).
- Make my homework: under the start CTA (desktop) and the mode cards'
  helper line (phone), plus once under the generated result for all three
  modes (make / check / guide).
- New deck wizard: under the summary helper (phone step 3) and the desktop
  CTA, next to Freeze my deck.
- AI grading (short answers): under the graded feedback; study, review and
  exam all share it.

Stored, already-generated content (deck page, study cards, explanations)
deliberately carries no note: the disclaimer belongs to the moment of
generation, not to browsing. Style: --text-subtle (documented at 5.6:1
light / 8.6:1 dark), 11.5px, centred, wraps to two lines at 360px, not
clickable, no icon.

Suites: chat (composer, phone + desktop), wizard (deck step 3 across
360/390 x en/cs x dark/light, homework start cards), phase3 (homework
trigger + result, phone + desktop), phase2 (stubbed grading feedback).
SW -> freezmo-v37. README: decision 50 + chat composer note.

Also fixes the deploy script's test instance: it now execs the server so
the cleanup kill reaps the real PID (the wrapper subshell left orphans
squatting on the test port — three from earlier sessions were found while
verifying this task), and the readiness poll checks the port serves the
NEW commit rather than just answering, so a leftover instance can never
be tested silently.
