feat: migrate traces/taps and route recording into Deployments config

ConfigSubTab now uses inner tabs (Agent / Infrastructure):
- Agent: observability settings, compress success, traces & taps table,
  route recording toggles
- Infrastructure: container resources, exposed ports, environment variables

This completes the Config tab consolidation — all features from the
standalone Config page now live in the Deployments tab.
