Matthew Jackson e83b7a3489 test: raise coverage across keydb, keydb_format, online, lib sources ...

Adds targeted unit tests for previously-uncovered branches: keydb load
failure classification (invalid-UTF-8 / unreadable path), zip extraction
success/no-cfg-member paths, write_atomic create/rename failure modes,
keydb_format hex-digit-parsing edge cases, iter_disc_entries, to_keydb_cfg
HC2 emission and empty-title/comment-field combinations, MultiSource::label,
and the online key-service client's SSRF-guard malformed-authority and
unresolvable-host paths, UK-as-string and VUK-derivation reply handling,
and get_fmts_indexes. Local line coverage moves from ~90.3% to ~92.1%.
