feat(license): enforce compute caps at DeploymentExecutor PRE_FLIGHT

Browse Source 
Adds ComputeUsage record + computeUsage() helper to LicenseUsageReader
that aggregates from PG. DeploymentExecutor.executeAsync runs three
assertWithinCap checks (max_total_cpu_millis, max_total_memory_mb,
max_total_replicas) right after config resolution. The existing
executor try/catch turns a LicenseCapExceededException into a FAILED
deployment with the cap message in the failure reason.

Adds ComputeCapEnforcementIT (HTTP-driven; @MockBean RuntimeOrchestrator,
since cap rejection short-circuits before any orchestrator call) plus
defensive license lifts in BlueGreenStrategyIT, RollingStrategyIT,
DeploymentSnapshotIT, and DeploymentControllerAuditIT so sequential
deploys under testcontainer reuse don't trip the new caps.

DEGRADED is now only set by `DockerEventMonitor` post-deploy, never by the executor. **License compute caps**: at PRE_FLIGHT (after `ConfigMerger.resolve`, before image pull / container creation) the executor consults `LicenseUsageReader.computeUsage()` (PG aggregate over non-stopped deployments) and runs three `LicenseEnforcer.assertWithinCap(...)` checks for `max_total_cpu_millis`, `max_total_memory_mb`, and `max_total_replicas`. A `LicenseCapExceededException` propagates to the surrounding `try/catch` which marks the deployment FAILED with the cap message in `deployments.error_message`.
- `DockerNetworkManager` — ensures bridge networks (cameleer-traefik, cameleer-env-{slug}), connects containers
- `DockerEventMonitor` — persistent Docker event stream listener (die, oom, start, stop), updates deployment status
- `TraefikLabelBuilder` — generates Traefik Docker labels for path-based or subdomain routing. Per-container identity labels: `cameleer.replica` (index), `cameleer.generation` (deployment-scoped 8-char id — for Prometheus/Grafana deploy-boundary annotations), `cameleer.instance-id` (`{envSlug}-{appSlug}-{replicaIndex}-{generation}`). Router/service label keys are generation-agnostic so load balancing spans old + new replicas during a blue/green overlap.
