* fix(desktop): read the PPA key add-apt-repository writes into Signed-By
On Ubuntu 24.04, add-apt-repository puts the PPA's armored key inside the
deb822 Signed-By field, and REA refused such repositories, so PPAs added the
standard way could not be exported. REA now reads that key by deb822 rules,
verifies the release with it through the same private gpgv keyring as key
files, as the entry's only candidate (as apt does), retains it as armored and
exports it as apt-keys/<name>.asc. A held key that does not verify is refused
with a reason that names no URL.

* test(desktop): check the held-key refusal's facts, not its sentence
The PPA refusal tests now assert that the reason names the sources file
and the release file and no URL, and that export carries that reason,
instead of comparing whole sentences.
