[AZ-897] [AZ-959] Relocate AZ-897 to ../ui, file AZ-959 backend slice

AZ-897 ("Build the first operator-facing UI for the GPS-denied
onboard system") was wrong-shop: the spec named React + Tailwind
but assumed it would land in gps-denied-onboard. The Azaion suite
already has a single React 19 SPA front-end at ../ui per
ui/README.md; spinning up a second React toolchain inside this
repo would have been parallel-pipeline duplication forbidden by
coderule.mdc.

Per user 2026-05-29 directive:

- Jira AZ-897 summary + description rewritten to UI-only scope in
  ../ui (adapted to take CSV + nadir-camera video uploads aligned
  with the AZ-894 CSV path). Full audit comment attached.
- Local AZ-897 spec deleted from this repo's todo/ and re-authored
  into ../ui/_docs/02_tasks/todo/AZ-897_replay_ui_web_form.md
  (left uncommitted there — ../ui repo's next autodev cycle picks
  it up).
- Filed AZ-959 (3 SP, todo/) to extend replay_api POST /replay to
  accept (video, csv) multipart + add GET /static/example-csv.
  Without this endpoint the relocated AZ-897 UI cannot drive the
  CSV-replay path.
- Linked AZ-959 'is blocked by' against AZ-897 Jira-side (verified
  via read-back: AZ-897 issuelinks now includes AZ-959 as blocker
  alongside the existing AZ-894 + AZ-896 dependency links).

Cycle-4 in-repo effort: −5 SP (AZ-897) + 3 SP (AZ-959) = −2 SP
net. AZ-897 itself remains open and active; its 5 SP now belong
to ../ui's cycle (the Jira ticket stays AZ-897 — no renumbering,
no duplicate, no Won't-Fix; just a scope + repo-home correction).

Touches: _docs/02_tasks/_dependencies_table.md (preamble third
bump narrative + AZ-959 row + totals to 184 / 584), _autodev
state pivots to AZ-959 as next implement-batch target. The
../ui-side spec write is intentionally uncommitted in that repo;
surface flagged in the chat summary.
