Add OPERATIONAL SAFEGUARDS headers, skip prefill during active rescans

Browse Source 
arr_full_rescan.sh, arr_cache_prefill.sh, and arr_rescan_monitor.sh were
missing the standard SAFEGUARDS header section other Arrs_Stack/Tools
scripts have. Also: arr_cache_prefill.sh now checks for an active rescan
before fetching, instead of doing a live fetch that arr_cache_write()
would just refuse to persist anyway -- avoids wasted API calls every
30min during a long rescan. arr_rescan_monitor.sh was also missing an
actual root check despite writing cache files; added it to match
convention rather than just document a safeguard that wasn't there.

# Root required — matches convention across Arrs_Stack/Tools/, writes cache files
# Arg validation — arr_type must be lidarr/sonarr/radarr, usage error otherwise
# Timeout, never waits forever — default 2h ceiling, override via second positional arg;
# on timeout, cache is left untouched rather than acted on stale
# --status mode — read-only, shows active rescan + cache age, waits/writes nothing
# --dry-run mode — shows what would be waited on, waits/writes nothing
# Triggers nothing — never starts a rescan itself, only watches one already running;
# use arr_full_rescan.sh or the arr's own UI/API to start one
