Parent button components (EditVendorButton, EditAccountButton, etc.) stay
mounted even when their AdminDialog closes — so pending was never cleared
on success, causing buttons to show 'Saving...' on the next open. The
payment confirm button (no dialog) was stuck in 'Confirming...' until the
page re-render eventually unmounted it. Added setPending(false) before
setOpen/router.refresh in every success path.

Increase the Prisma interactive transaction timeout from the default 5s
to 30s so that the four sequential nullification + delete queries complete
reliably on a seeded database (P2028 timeout was the root cause).
Wrap the transaction in a try/catch so that if a timeout does still occur
the user sees "Delete timed out — please try again." instead of an
unhandled 500 that previously manifested as the misleading "referenced in
submitted or active purchase orders" error message.
