feat(calibrate-serve): live enroll-over-HTTP (POST /enroll/anchor + /enroll/status)

Closes the last HTTP gap — the appliance can now drive the ENTIRE calibration
pipeline over HTTP without the CLI:
  baseline (start/stop) -> enroll/anchor x8 -> room/train -> room/state

- POST /enroll/anchor { room_id, baseline, label, duration_s? }: the ingest task
  loads the baseline (sanitized name under output_dir), captures the anchor for
  the duration against it (AnchorRecorder + per-frame series), runs the quality
  gate, and on completion replies with the verdict + accumulates the AnchorFeature
  in an in-server enrollment map keyed by room_id. Re-prompts on rejection.
- GET /enroll/status?room=<id>: accepted anchors, next, complete.
- POST /room/train now falls back to the in-server enrollment when anchors[] is
  omitted.

Validated live (ESP32-S3): capture baseline -> enroll stand_still (271 frames,
6s) -> gate correctly rejects "no person detected (presence_z 0.90 < 1.50)"
relative to a same-occupancy baseline (a clean empty-room baseline is the
documented on-target prerequisite). Builds clean; CLI tests pass.

A single background task owns the UDP socket + recorder (handlers talk to it over an mpsc channel +
shared status snapshot), so the API is non-blocking. Enrollment/train/room-state are CLI today
(`enroll`/`train-room`/`room-watch`); exposing them over the same API is a small, additive follow-on —
**recommended appliance enhancement** (see §6).
shared status snapshot), so the API is non-blocking. **The full pipeline is now drivable over HTTP** — baseline (`start`/`stop`) → `enroll/anchor` (×8) → `room/train``room/state` — so the appliance UI needs no CLI. (The CLI `enroll`/`train-room`/`room-watch` remain for scripted/headless use.)
