feat(#374): add telemetry config to docker-compose and .env

- Add MOSAIC_TELEMETRY_* variables to .env.example with descriptions
- Pass telemetry env vars to api service in production compose
- Pass telemetry env vars to coordinator service in dev and swarm composes
- Swarm composes default to production URL (https://tel-api.mosaicstack.dev)
- Dev compose includes commented-out telemetry-api service placeholder
- All compose files default MOSAIC_TELEMETRY_ENABLED to false for safety
