terem42 7e8b500420 fix(filemeta): classify xl.meta CRC mismatch as FileCorrupt so heal repairs it (#5838)
A failed CRC means the metadata bytes on disk are not the bytes that were
written — bitrot. Raising it as Error::other() surfaces a generic Io error,
which should_heal_object_on_disk does not recognise as heal-worthy: the drive
is skipped, disks_to_heal_count stays 0, heal_object returns ok, and the
corrupted xl.meta is never rewritten — while the scanner re-submits the same
no-op heal every deep-scan cycle. An explicit admin deep heal fails the same
way, so no heal path repairs metadata bitrot, and every one of them reports
success.

check_xl2_v1 already classifies a short or wrong-magic header as FileCorrupt
for exactly this reason (#5716); this completes the pattern for the two CRC
sites. The existing From<rustfs_filemeta::Error> for DiskError conversion maps
the variant to DiskError::FileCorrupt, which the heal path already handles.
The previously silent is_indexed_meta site now logs the mismatch (structured
event shape) like unmarshal_msg does.

Regression test: corrupt one byte of a marshalled FileMeta and assert
unmarshal_msg reports FileCorrupt; fails on the previous code, which returned
Io(Other).

Verified end-to-end on a 3-node / 12-drive EC:4 cluster: xl.meta corrupted on
2 of 12 drives via dd, admin deep heal — before this change the heal returns
ok with the corruption intact and the scanner loops forever; with it, both
copies are rewritten (decode-identical to the healthy quorum), the object
reads back byte-correct, and a follow-up heal reports all twelve drives
clean.
