Set default ProxmoxVE raw URL in PVE-UPS & fix var_cpu sorting (#16689)

* Set default ProxmoxVE raw URL in UPS script

Define `_CS_DEFAULT_URL` at the top of `ct/pve-ups.sh` and remove the outdated bootstrap comments, aligning the script with the newer URL-default pattern used for script sourcing.

* Branch var_cpu by OS where the two variants actually differ

The merged scripts branch var_ram, var_disk and var_version on var_os but
left var_cpu above the branch, so both variants inherited the Debian value.
On Vaultwarden that meant an Alpine container was told it wanted four cores
for an update that runs apk and restarts a service.

Only seven scripts are affected. Comparing each merged script against the
alpine-* script it replaced, 22 of the 29 already had the same CPU count on
both sides, so moving the line there would be churn with no behaviour change.
These seven did not:

  docker, forgejo, ironclaw, syncthing, transmission, zigbee2mqtt   2 -> 1
  vaultwarden                                                       4 -> 1

The Alpine values are the ones those scripts carried before the merge, read
back out of the deleted alpine-* files rather than picked. The Debian arm
keeps what it has now.

Needs the matching core change: until build.func derives var_os inside a
container, an update never reaches the Alpine arm at all.

* fix: source url

* Update script to source build functions from URLs
