Chris 4e7a8fabb8 fix(ecstore): repair buckets left with only an incarnation sidecar (#8008)
The legacy bucket metadata migration writes the `.bucket-incarnation`
sidecar before `.metadata.bin`. A crash or a lost namespace lease between
the two writes left the bucket with a sidecar and no metadata, and every
later load failed closed with "bucket incarnation sidecar exists without
bucket metadata", so the bucket answered 500 to every request on every
node with no repair path (rustfs/rustfs#8003).

Load the sidecar-only state as a legacy bucket so the migration runs
again. The migration and the force-create path re-read the sidecar under
the transaction lock and keep its incarnation when persisting the
metadata, so the retry never replaces an identity other nodes fenced on.
A retired incarnation is never adopted: it is residue of a deleted
bucket, and re-publishing it would let heal reclaim the new objects.
