UmlautAdaptarr: use the Debian 13 Microsoft repo with its 2025 signing key (#16077)

* UmlautAdaptarr: use the Debian 13 Microsoft repo with its 2025 signing key

The container is Debian 13 (var_version 13) but the script configures the
Microsoft debian/12 prod repo with suite bookworm.

The move to debian/13 was reverted in #8392 because apt reported "OpenPGP
signature verification failed" (#8385), diagnosed at the time as Microsoft
not having populated the trixie repo. The actual cause was the signing key:
debian/13/prod is signed by EE4D7792F748182B (microsoft-2025.asc), while the
script kept microsoft.asc (EB3E94ADBE1229CF). The suite and URL were changed
but the key was not.

The trixie repo carries the required packages at current patch level
(dotnet-sdk-8.0 8.0.423-1, aspnetcore-runtime-8.0 8.0.29-1).

This makes the call identical to the six other scripts already on the
Debian 13 Microsoft repo (technitiumdns, igotify, mail-archiver, rdtclient,
fileflows, immichframe).

* UmlautAdaptarr: migrate existing containers to the Debian 13 repo on update

Per review feedback: the install-side fix only helps new containers.
Existing ones keep the Debian 12 repo indefinitely, because update_script
only fetches a GitHub release and never touches apt.

Repoints them when the stale Debian 12 repo is detected, mirroring the
conditional setup_deb822_repo calls in ct/technitiumdns.sh and
ct/fileflows.sh. The guard makes this a no-op once migrated.

setup_deb822_repo's microsoft* globs also clear the pre-#9839
microsoft-prod.sources layout; its key lived in /usr/share/keyrings,
which cleanup_old_repo_files does not cover, so it is removed explicitly
as ct/technitiumdns.sh does.
