M1(verified): live smoke test all 9 steps green + 6 compose/Dockerfile fixes

Smoke test ran on 2026-06-13 against the full docker-compose stack.
All 9 verification steps from M1_VERIFICATION.md pass. See
M1_SMOKE_LOG.md for the per-step results and the issues I fixed
mid-run (BuildKit shell-redirect, Go 1.25 base image, emqx tag,
emqx healthcheck, nats monitoring flag, host port conflicts).

End-to-end proven: signed webhook -> ingestd -> NATS alerts.<co>
-> routerd broadcast -> NATS deliveries.fcm.<co> -> deliverd ->
fakefcmd -> deliveries row (status=sent). 1530 deliveries in the
loadgen burst, 0 failures, dedupe_count increments correctly.

Bumps SPEC §23 M1 row to 'shipped'.

+# M1 Smoke Test — Live Results
+
+Run on 2026-06-13, host interserver2. All 9 steps from
+`M1_VERIFICATION.md` passed.
+
+## Step results
+
+| # | step | result |
+|---|---|---|
+| 1 | `docker compose build` | ✅ all 6 images built |
+| 1 | `docker compose up -d` | ✅ all 10 services up (postgres, redis, nats, emqx, clickhouse, fakefcmd, ingestd, routerd, deliverd, admind) |
+| 1 | `docker compose up seed` | ✅ `seed: ok` |
+| 2 | verify companies/individuals/fcm_tokens | ✅ 1+1+1 rows |
+| 3 | fakefcmd `/health` | ✅ `{"status":"ok","received":0,"failed":0}` |
+| 4 | signed POST to ingestd | ✅ `202 {"alert_id":"0000019ec2...","dedupe_count":1}` |
+| 5 | `deliveries` row appears | ✅ `status=sent, attempts=1, channel=fcm` |
+| 6 | fakefcmd log | ✅ `alert_id=0000019ec2... title="Disk full on db-prod-03"` |
+| 7 | bad signature | ✅ `401` |
+| 7 | payload > 256KB | ✅ `413` |
+| 7 | invalid JSON | ✅ `400` |
+| 7 | bad severity | ✅ `400` |
+| 8 | loadgen-http 50/s × 30s | ✅ 1529 sent, 0 failed, 0 rate_limited |
+| 8 | deliveries count after burst | ✅ 1530 sent (1529 burst + 1 step-4) |
+| 9 | same dedupe_key 3x | ✅ `dedupe_count: 1, 2, 3` |
+
+## Issues found and fixed during the live run
+
+| # | issue | fix |
+|---|---|---|
+| 1 | `Dockerfile` `COPY ... 2>/dev/null \|\| true` not supported by BuildKit | removed the shell redirect; only copy the file that exists |
+| 2 | `go.mod` requires Go 1.25; Docker base image was 1.24 | bumped Dockerfile `FROM golang:1.25-alpine` |
+| 3 | `emqx/emqx:5-alpine` tag no longer exists in Docker Hub | pinned to `emqx/emqx:5.10.4` (latest v5 stable) |
+| 4 | EMQX 5.10 healthcheck `wget` against `/api/v5/status` requires auth | swapped to `bash /dev/tcp/127.0.0.1/1883` — the MQTT TCP port is the real liveness signal |
+| 5 | `nats:2.10-alpine` healthcheck failed because HTTP monitoring needs explicit `-m 8222` flag | added `-m 8222` to the nats command line |
+| 6 | Host already has a redis on `:6379` and a postgres on `:5432`; docker proxy failed to bind | changed compose to `expose:` (no host port mapping) for postgres + redis. App services reach them via docker DNS. |
+
+## Honest notes
+
+- The `emqx` container shows `health: starting` indefinitely in step 1; the
+  TCP probe is succeeding (we can connect to 1883) but docker's
+  healthcheck machinery seems slow to mark it healthy. Doesn't block
+  M1. Will revisit in M4.
+- The `seed` container is a one-shot sidecar that doesn't restart. To
+  re-run it: `docker compose up seed`.
+- Default `BA_POSTGRES_PASSWORD` and `BA_REDIS_URL` in compose are
+  dev-only values; production overrides via `.env` are out of M1
+  scope.
