Save and SaveAdmin now propagate loadBundle errors instead of silently
overwriting a corrupt file (data-loss fix). Tests added for both paths.
reportStats logs a Debug on RunStats failure; r in runJob gets a comment
explaining the prune-runner asymmetry; runner_test comment tightened.
RunCheck and RunUnlock were calling sendFinished before reportStats,
inverting the required job.started → log.stream → repo.stats →
job.finished envelope order. Move reportStats ahead of sendFinished in
both functions to match the pattern already correct in RunPrune.
Strengthen TestRunCheckShipsCheckStatus, TestRunCheckErrorsFoundShipsErrorsStatus,
and TestRunUnlockClearsLock with the same position-index ordering
assertions used by TestRunPruneShipsExpectedEnvelopes; these assertions
would have failed against the pre-fix code.
Extract resticEnv/sendStarted/streamHandler/sendFinished helpers to remove
boilerplate duplication across Run* methods. Add RunPrune (ships repo.stats
with LastPruneAt before job.finished), RunCheck (ships stats with
LastCheckStatus/LockPresent regardless of outcome), RunUnlock (ships
LockPresent=false on success), and reportStats (fills size fields via
RunStats when caller didn't populate them).
Wire JobPrune/JobCheck/JobUnlock into the dispatcher switch; teach
MsgConfigUpdate about the Slot discriminator for admin vs repo creds;
add strconv import for subset-pct parsing.
