* fix: confirm a pid is still ours before signalling it

#7574 added the still-running guard to dsstats but left six byte-identical
siblings signalling a pid straight out of the processes table. After a crash or
a power loss the row survives, the pid is recycled by an unrelated daemon, and
the next start SIGTERMs a stranger. That is issue #7425, still live in rrdcheck,
boost, poller_commands, float_rrdfiles, poller_reindex_hosts and
rebuild_poller_cache.

Wrap each kill in cacti_process_still_running(), matching the dsstats shape, and
leave unregister_process() outside the guard so a stale row is still cleaned up.

Cover all seven with a test that walks every kill site, so a new variant cannot
reintroduce it.

* test: assert the guard plainly

toContain() takes needles rather than a failure message, so the file name was
being asserted as a second required substring and the test always failed.

* docs(poller): describe required lock parameters
