scheduler: orch-god toggle model — children managed via master.conf

When orch is ON (god mode):
- Children's toggle state is read from master.conf comment status
- Toggling a child comments/uncomments its line in the *_SCRIPTS array
- Child crons are suppressed in vv_cron_rebuild — orch is the sole trigger
- Children not found in any *_SCRIPTS array are shown disabled (read-only)

When orch is OFF:
- All children flip to off; schedule.json updated immediately
- A child with a cron value + enabled toggle gets its own independent cron entry
- A child with no cron does nothing when enabled

New: vv_conf_script_map() — cached per-request scan of master.conf arrays
New: vv_parse_conf_array_full() — includes commented entries (disabled scripts)
New: vv_conf_toggle_script() — comments/uncomments a script line in master.conf
New: api/conf_toggle.php — endpoint for child toggle → master.conf write
