Dead-code cleanup + tests for fusion/depth/OSM/training/fingerprinting

Reviewer point #11 (PR #405): remove the `#![allow(dead_code)]`
silencing added in 8eb808d and fix the underlying issues.

- Delete csi.rs: duplicate of csi_pipeline.rs with incompatible wire
  format (JSON vs ADR-018 binary). csi_pipeline is the real path.
- Delete serial_csi.rs: never referenced by any module.
- Drop Frame.timestamp_ms (unread), AppState.csi_pipeline (unread),
  brain_bridge::brain_available (caller-less), fusion::fetch_wifi_occupancy
  (caller-less) — these had no runtime users.
- Drop crate-level #![allow(dead_code)] from camera.rs, depth.rs,
  fusion.rs, pointcloud.rs.

Tests (target: 8-12, actual: 15 unit + 9 geo unit + 8 geo integration
= 32 total, all pass):

- parser.rs: 5 tests (v1/v6 magic roundtrip, wrong magic, truncated
  header, truncated payload).
- fusion.rs: 2 tests (non-overlapping merge, voxel dedup).
- depth.rs: 2 tests (2x2 backproject → 4 points at z=1, NaN rejected).
- training.rs: 4 tests (rejects `..`, accepts relative child, refuses
  TrainingSession::new("../etc/passwd"), accepts a clean tmpdir).
- csi_pipeline.rs: 2 tests (set_light_level toggles is_dark,
  record_fingerprint stores and self-identifies).
- osm.rs: 3 tests (parse_overpass_json minimal fixture, rejects
  malformed payload, fetch_buildings rejects > MAX_RADIUS_M).
