dconf: add dbus-broker support by improving D-Bus session discovery (#11772)

* dconf: add dbus-broker support by improving D-Bus session discovery

Extend DBusWrapper._get_existing_dbus_session() to check:
1. DBUS_SESSION_BUS_ADDRESS in the current process environment
2. /run/user/<uid>/bus (canonical socket for systemd and dbus-broker)
3. Process scan (legacy fallback, as before)

Also add _validate_address() to support both dbus-send and busctl,
making the module work on systems using dbus-broker (e.g. Fedora Silverblue)
where no process exposes DBUS_SESSION_BUS_ADDRESS in its environment.

Fixes: https://github.com/ansible-collections/community.general/issues/495

* dconf: restore dbus validator requirement and example usage

Restore fail_json when neither dbus-send nor busctl is available,
preserving the original hard requirement for a validator binary.
Restore the example invocation in DBusWrapper docstring.
