Fix bridged mode setting incorrect bridge parameter

When bridged mode is enabled, the bridge parameter in hostapd.conf
was set to "1" instead of "br0", causing authentication failures.

This fix introduces a separate bridgeName parameter for the hostapd
configuration while maintaining the boolean bridge parameter for
dnsmasq and dhcpcd services.

Fixes #2021
