Isaac ConnorandClaude Opus 5 bd9d693602 fix: report why CpuUsage cannot read /proc/stat and stop warning every interval ...

/proc/stat is invisible to any process in a mount namespace set up with
ProcSubset=pid, which is systemd's default hardening for apache. Daemons
started from the web ui are forked off mod_php and inherit it, so zmstats
fell through to the top fallback, which reads /proc/stat as well and so
produced no output either.

Separate the missing-file case from the failed-open case so the message
names the likely cause instead of printing a $! that a failed -e never set.

Emit the warning once per process rather than once per
ZM_STATS_UPDATE_INTERVAL. The condition does not clear itself, so it was
filling zmstats.log with the same three lines a minute.

split() on an empty $top_output returns an empty list, leaving all four
values undef, so each fallback cycle also emitted four "Use of
uninitialized value" warnings under -w. Default them before use.
