Commit Message

Skip the machine-snapshot commit on a concurrent version race

Two near-simultaneous check-ins from the same machine + source can both pick the
same next version; one wins, the other hits the (serial_number, source, version)
unique constraint. The manager already returned quietly when the winner had stored
an identical snapshot, but raised MTOError when it had stored a different one,
500-ing the check-in (~1/day on the busiest MDM tenant, e.g. santa preflight).

A differing snapshot just means a tree field (IP/OS/user/apps) changed inside the
race window; the current snapshot is already up to date and the next check-in
reconciles, so log and skip instead of raising. No MTOError, no 500.
