Bitcoin Knots failed to start with "failed to set loopback adapter up"
because cap-drop=ALL removed NET_BIND_SERVICE, which rootless podman
needs for network namespace setup.
- Add NET_BIND_SERVICE to Bitcoin/LND/Fedimint capabilities
- Add NET_BIND_SERVICE as default for ALL apps (rootless podman needs it)
- UID mapping fix from previous commit also included
