fix: rate-limit CSI sends and add ENOMEM backoff to prevent crash (#132 )

The CSI callback fires for every WiFi frame in promiscuous mode
(100-500+ fps). Each call invoked sendto() synchronously, exhausting
lwIP packet buffers (errno 12 = ENOMEM). The rapid-fire failures
cascaded into a LoadProhibited guru meditation crash.

Two fixes:

1. csi_collector.c: Rate-limit UDP sends to 50 Hz (20ms interval).
   CSI frames arriving between sends are dropped — the sensing
   pipeline only needs 20-50 Hz.

2. stream_sender.c: When sendto fails with ENOMEM, suppress further
   sends for 100ms to let lwIP reclaim buffers. Logs the backoff
   event and resumes automatically.

Closes #127

fix(docker): Update Dockerfile paths from src/ to v1/src/

The source code was moved to v1/src/ but the Dockerfile still
referenced src/ directly, causing build failures. Updated all
COPY paths, uvicorn module paths, test paths, and bandit scan
paths. Also added missing v1/__init__.py for Python module
resolution.

Fixes #33

feat(adr-018): ESP32-S3 firmware, Rust aggregator, and live CSI pipeline

Complete end-to-end WiFi CSI capture pipeline verified on real hardware:

- ESP32-S3 firmware: WiFi STA + promiscuous mode CSI collection,
  ADR-018 binary serialization, UDP streaming at ~20 Hz
- Rust aggregator CLI binary (clap): receives UDP frames, parses with
  Esp32CsiParser, prints per-frame summary (node, seq, rssi, amp)
- UDP aggregator module with per-node sequence tracking and drop detection
- CsiFrame bridge to detection pipeline (amplitude/phase/SNR conversion)
- Python ESP32 binary parser with UDP reader
- Presence detection confirmed: motion score 10/10 from live CSI variance

Hardware verified: ESP32-S3-DevKitC-1 (CP2102, MAC 3C:0F:02:EC:C2:28),
Docker ESP-IDF v5.2 build, esptool 5.1.0 flash, 20 Rust + 6 Python tests pass.
