radius-admin: Login-Time text input css width
radius-admin: use += operator in radgroupcheck
radius-admin: use ':=' operator for Group

Use := operator for Group attribute in radgroupcheck.

It's a "dummy"/unnecessary row in the table, useful for an
attribute-less / stub group.

Using '=' will result in a forced conversion to '==',
which means a match we certainly don't want...

(no access-request RADIUS packet from the NAS contains a Group
attribute!)

listen on any to ease testing (secure this apart)

A good idea would be listening on 0.0.0.0 only in development...

In the meanwhilem use, well, a firewall and/or a VPN ;)
