Wraps the dominant pattern (try { await fn } catch { pushToast(errMessage,
'error') }) for the 5 admin/+page.svelte handlers that surface errMessage
directly: onApprove, onReject, onResolve, onDeleteFile, onDeleteLidarr.
Tighter scope than originally planned — the 3 handlers in
admin/users/+page.svelte (onToggleAutoApprove, onGenerateInvite,
onRevokeInvite) use errCode + verb prefix ("Generate failed: ${code}")
which is structurally different and would change UX wire output if
forced through the helper. Skipping them keeps behavior identical.
The helper SWALLOWS errors so callers no longer need try/finally for
busy-state — `saving = true; await runMutation(...); saving = false;`
is correct because runMutation can't throw.
