fix: implement DISABLE_CADDY env var in Docker entrypoint (#629) (#637)

## Summary

Implements the `DISABLE_CADDY` environment variable in the Docker
entrypoint, fixing #629.

## Problem

The `DISABLE_CADDY` env var was documented but had no effect — the
entrypoint only handled `DISABLE_MOSQUITTO`.

## Changes

### New supervisord configs
- **`supervisord-go-no-caddy.conf`** — mosquitto + ingestor + server (no
Caddy)
- **`supervisord-go-no-mosquitto-no-caddy.conf`** — ingestor + server
only

### Updated entrypoint (`docker/entrypoint-go.sh`)
Handles all 4 combinations:
| DISABLE_MOSQUITTO | DISABLE_CADDY | Config used |
|---|---|---|
| false | false | `supervisord.conf` (default) |
| true | false | `supervisord-no-mosquitto.conf` |
| false | true | `supervisord-no-caddy.conf` |
| true | true | `supervisord-no-mosquitto-no-caddy.conf` |

### Dockerfiles
Added COPY lines for the new configs in both `Dockerfile` and
`Dockerfile.go`.

## Testing

```bash
# Verify correct config selection
docker run -e DISABLE_CADDY=true corescope
# Should log: [config] Caddy reverse proxy disabled (DISABLE_CADDY=true)

docker run -e DISABLE_CADDY=true -e DISABLE_MOSQUITTO=true corescope
# Should log both disabled messages
```

Fixes #629
