Oleksandr Bezdieniezhnykh 1d18e25cf4 [AZ-959] replay_api: POST /replay (video,csv) + /static/example-csv
Extend the AZ-701 replay_api POST /replay endpoint so AZ-897 (now
in ../ui repo) can drive the AZ-894 CSV-replay path. The endpoint
keeps full back-compat for tlog clients and adds:

- (video, tlog) OR (video, csv) multipart with strict XOR enforced
  at the API boundary (AC-2 / AC-3 → 400 multipart_missing_field)
- validate_csv_kind: rejects malformed CSV schema at boundary by
  scanning the header line for AZ-896 required tokens; messages
  point at csv_replay_format.md (AC-4)
- ReplayInputs DTO: tlog_path / csv_path are now Path | None with
  XOR re-enforced in __post_init__ for internal callers
- JobStorage reserves both input.tlog and input.csv paths; handler
  writes exactly one
- SubprocessReplayRunner.run dispatches --imu vs --tlog argv (AC-1)
- _maybe_render_report dispatches load_csv_ground_truth vs
  load_tlog_ground_truth; CsvGpsFix and TlogGpsFix have
  field-compatible shapes for the GroundTruthRow adapter (AC-6)
- GET /static/example-csv serves the AZ-896 reference CSV; honours
  REPLAY_API_EXAMPLE_CSV_PATH env, falls back to source-checkout
  layout, returns 503 with example_csv_unavailable when neither
  resolves to a readable file. No auth required (AC-5)

Tests: 27/27 unit tests green:
- 18 pre-existing tlog-path tests unchanged (AC-7)
- 9 new tests covering ACs 1-6 + validate_csv_kind isolation

Deferred (NOT silently fixed; reported to user as end-of-turn
notes for scope discipline):

- gps-denied-render-map only consumes binary tlog truth today, so
  CSV-path jobs return map_html_url=None. Extending render-map to
  dispatch on truth-file extension is AZ-700 follow-up territory.
- ReportContext.tlog_path field is now overloaded as the
  "ground-truth source path"; the rendered report still labels
  the line "Tlog: <csv_path>" which is cosmetically misleading
  for CSV runs. Field rename + label fix is AZ-699 follow-up.

Bookkeeping: AZ-959 spec moved todo/ → done/, dep-table preamble
fifth bump documents what landed + what's deferred, state.md
records batch 5 complete and what comes next.
