All containers now get CHOWN+FOWNER+SETUID+SETGID+DAC_OVERRIDE+NET_BIND_SERVICE
as the default cap set. Rootless podman needs these for:
- CHOWN/FOWNER/DAC_OVERRIDE: file ownership in mapped UID namespace
- SETUID/SETGID: internal user switching (entrypoint scripts)
- NET_BIND_SERVICE: port binding in network namespaces
Tested on .198: Grafana, Vaultwarden, Bitcoin Knots all start successfully.
Previously failed with "Permission denied" or "loopback adapter" errors.
