Dilshod Rasulov abc819294c fix(images): unblock guest-exec in RHEL-family cloud images ...

The RHEL-family qemu-guest-agent package starts the agent with an allow-list
that omits guest-exec, guest-exec-status and guest-file-* (FILTER_RPC_ARGS in
/etc/sysconfig/qemu-ga; older packages spelled the same restriction as
BLOCK_RPCS or BLACKLIST_RPC). The agent answered "The command guest-exec has
been disabled for this instance", so running scripts in a VM, assigning extra
IP addresses and growing the filesystem after a disk resize did not work on
Rocky Linux, AlmaLinux, CentOS Stream and Fedora guests.

- patch-cloud-images.sh: clear all three variants while building the mirror
  (UNBLOCK_RPC=0 opts out) and add an ONLY filter to rebuild only part of the
  catalog. Three `[ ... ] && ...` statements that aborted the script under
  set -e are now plain ifs -- the one before mirrors.json generation killed
  every run that passed BASE_URL
- builtin.py: point the five RHEL-family amd64 entries at the rebuilt mirror
  release 2026-08-22 with their new checksums. Ubuntu and Debian images are
  unaffected and stay in the previous releases, so older panel versions keep
  working
- client.py: annotate the Proxmox error with what to clear inside the guest,
  the raw message names neither the file nor the variable
- WIKI, CHANGELOG: document the restriction and the unblock command
