ci: pushover notification on success too

Single notify step now runs for both success and failure
(when.status: [success, failure]), branching on
CI_PIPELINE_STATUS for the title. Success uses Pushover
priority -1 (quiet) so passing-build pings don't alert at
night; failures stay at priority 0 (default).
