The provider remap moves a port; it does not bind it to loopback

Browse Source 
postgres and lavinmq carried 127.0.0.1: in their remap, and it broke a consumer
on a node that has no substrate to collide with. A module is told to reach its
provider at <node>.internal, that name is the node's overlay address, and a
provider listening only on loopback refuses it — letta on ace failed with 'is the
server running on that host and accepting TCP/IP connections?' while postgres sat
healthy beside it.

The collision needed a different port, which is what every other entry here does.
The address was never part of it, and it made the provider unreachable by the one
name the mesh hands its consumers.
