Gmer4Lfe bf3e7cc2c4 Storage-mode awareness pass + doc update for System_Essentials through Partnership
All state/data file paths in scripts and PHP now resolve via STATE_DIR / DATA_DIR /
PERSISTENT_CONF_CACHE instead of hardcoded /boot/config/ or /tmp/ paths, so the
ecosystem works in both internal and appdata storage modes.

PHP layer (watchdog.php, partnership.php, fallback.php, monitor.php, snapshot.php,
config.php): all state reads switched to STATE_DIR constant; remote state reads use
the new vv_remote_state_cmd() helper which resolves the remote's SCRIPTS_DIR via
their varaverk.cfg before building the path.

conf_sync.sh: fixed SCRIPTS_ROOT → SCRIPTS_DIR bug on MY_CONF path; added
_remote_scripts_dir() to resolve partner's SCRIPTS_DIR before SCP pull.

fallback.php page: added controls card (PARTNERSHIP_ENABLED, FALLBACK_ENABLED,
FALLBACK_RSYNC_ENABLED toggles), status grid, and settings card.

README and Manual updated for System_Essentials, Watchdogs, Fallback, Rsync,
Media, Monitors, Orchestrators, Partnership: added new scripts (conf_sync,
conf_cache_save/restore, conf_cache_watchdog, play_state_sync, start_webhook_listener,
upgrade_webhook_handler), corrected all stale /boot/config/ state file paths to
$STATE_DIR/$DATA_DIR, noted webgui/php_fpm/mover/user_scripts scripts moved to
Plugin/unraid/System_Essentials, fixed start_webhook_listener.sh header (Node.js,
not PHP -S).

# PURPOSE
# ─────────────────────────────────────────────────────────────────────────────
# Maintains the persistent partner conf backup at $PERSISTENT_CONF_CACHE.
# Runs every 15 minutes via SYSTEM_WATCHDOG_SCRIPTS.
#
# When remote is OFFLINE:
# Writes/refreshes partner confs from RAM cache → persistent location.
# Means if this host reboots while remote is still down, conf_cache_restore.sh
# can load the partner vars into RAM so fallback.sh has what it needs.
#
# When remote is ONLINE:
# Removes the persistent backup if present — not needed, conf_sync.sh will
# pull fresh on next boot.
#
# Silent when remote is online and no backup exists (normal state).
# No-op when FALLBACK_ENABLED=false or CONF_SYNC_ENABLED=false.
