Ok, both output ports have the same priority. The UCM configuration could
provide the priority, but your UCM configuration doesn't do that. I don't think
it's a good idea to use UCM as the priority authority anyway, because if the
system has both UCM and non-UCM cards, the priorities between the cards
wouldn't be comparable (and I doubt that the priorities between two different
UCM cards would be comparable either). Instead, PulseAudio should determine the
priority based on the device types. AFAIK, UCM doesn't currently provide device
type information, so that's something to fix in UCM. As a workaround,
PulseAudio could guess the device type from the device name.

I don't know why the Handset Microphone port has higher priority than the
default 100. Does your UCM config have any differences to what's currently in
alsa-lib master branch?

Regarding the simultaneous output to both speakers and headphones: I suppose
this happens only after boot? The UCM config looks like it has appropriate mute
commands in the DisableSequence sections for both devices. I believe the
disable sequences aren't executed during boot, however, so the default mixer
configuration in bytcr-rt5651.conf should be changed to mute all outputs.
