Alex Vanderpot 6c9dbf222f Accept numeric SNR/len/RSSI in MeshCore packets messages
The packets-message parser typed every metric field as a string, so any
gateway that emits SNR, RSSI, len, payload_len, packet_type, score, or
duration as a bare JSON number (including negative and fractional values)
failed json.Unmarshal and dropped the entire packet — including the raw
bytes we need.

Introduce a flexString type that accepts either a JSON string or a bare
number (kept verbatim as text) and apply it to those numeric metric
fields. Add tests covering both the numeric and string encodings.

Alex Vanderpot 7cea182c6d ingest: batch ClickHouse inserts to stop MQTT flapping & packet loss (#41)
* ingest: batch ClickHouse inserts to stop MQTT flapping & packet loss

The meshcore handler did a synchronous per-message ClickHouse insert on
paho's single inbound goroutine. At ~86ms/insert (single-row inserts +
async_insert wait + materialized views) the goroutine couldn't keep up
with the high-volume letsmesh feed, so it stalled past PingTimeout and
paho declared "pingresp not received" and reconnected — ~847 cycles in
19.5h, ~45% downtime, ~50% of letsmesh packets lost. The low-volume
davekeogh broker never saturated the goroutine and was unaffected.

Decouple receipt from insertion: the handler now enqueues decoded rows
onto a buffered channel and a single background writer flushes them to
meshcore_packets in batched native inserts (every MESHCORE_BATCH_FLUSH_
SECONDS or MESHCORE_BATCH_MAX_ROWS rows). The inbound goroutine never
blocks, so PINGRESP is always processed in time.

- New batch writer with env-configurable flush interval / max rows /
  buffer size (MESHCORE_BATCH_* ), wired in docker-compose.
- Drop server-side async_insert (redundant once we batch app-side).
- Bump PingTimeout 10s -> 20s (env MQTT_PING_TIMEOUT_SECONDS) for margin
  against Cloudflare WebSocket buffering jitter.
- Enqueue is non-blocking; rows are dropped+counted only if the buffer
  fills (ClickHouse unavailable). A failed batch is dropped and retried
  by the next flush (native blocks commit atomically).

* ingest: make MQTT KeepAlive configurable (MQTT_KEEPALIVE_SECONDS)

As a near-silent subscriber, paho emits a PINGREQ roughly every KeepAlive
seconds; lowering it sends client->server frames more often to keep the
Cloudflare-proxied WebSocket path warm in both directions, a lever for the
residual mid-stream "pingresp not received" stalls on the letsmesh broker.
Default unchanged (30s); wired through docker-compose.

* ingest: add configurable MQTT write timeout (MQTT_WRITE_TIMEOUT_SECONDS)

Bounds PINGREQ/SUBSCRIBE writes so a stalled write through the Cloudflare
WebSocket proxy can't hang the client. Default 0 (paho's existing no-timeout
behavior); wired through docker-compose. Recommended ~20s when behind a
buffering reverse proxy.

Alex Vanderpot 384f7f8b14 ingest: fix go module path to match repo
Module is now github.com/ajvpot/meshexplorer/ingest (the code lives under
ingest/ in the meshexplorer repo), updated from the old standalone
clickhouse-meshingest path. build/vet/test pass.

Alex Vanderpot 83978609f0 ingest: meshcore MQTT->ClickHouse stack
Vendor the ingest service under ingest/ and move the web app under meshexplorer/.
The ingest builds the meshcoreingest daemon and the goose migration runner,
applies the meshcore ClickHouse schema (packets, adverts, unified node view),
and loads its MQTT broker list and ClickHouse settings entirely from environment
variables (MQTT_BROKERS as a JSON array, CLICKHOUSE_*). No credentials are baked
into the source.
