gossmap: keep capacity for locally-generated channels as well.
...
It was weird not to have a capacity associated with localmods channels, and
fixing it has some very nice side effects.
Now the gossmap_chan_get_capacity() call never fails (we prevented reading
of channels from gossmap in the partially-written case already), so we
make it return the capacity. We do this in msat, because that's what
all the callers want.

gossmap-compress: sort nodes into most to least as intended.

Interestingly, compressed sizes don't change, but uncompressed does:

This helps code using generate_gossip_store() too, since it can map its identifiers
to the nodeids which were used.
