fix: unify container/agent log identity and fix multi-replica log capture

Four logging pipeline fixes:

1. Multi-replica startup logs: remove stopLogCaptureByApp from
   SseConnectionManager — container log capture now expires naturally
   after 60s instead of being killed when the first agent connects SSE.
   This ensures all replicas' bootstrap output is captured.

2. Unified instance_id: container logs and agent logs now share the same
   instance identity ({envSlug}-{appSlug}-{replicaIndex}). DeploymentExecutor
   sets CAMELEER_AGENT_INSTANCEID per replica so the agent uses the same
   ID as ContainerLogForwarder. Instance-level log views now show both
   container and agent logs.

3. Labels-first container identity: TraefikLabelBuilder emits cameleer.replica
   and cameleer.instance-id labels. Container names are tenant-prefixed
   ({tenantId}-{envSlug}-{appSlug}-{idx}) for global Docker daemon uniqueness.

4. Environment filter on log queries: useApplicationLogs now passes the
   selected environment to the API, preventing log leakage across environments.
