Push master.conf to all partners immediately on raw-editor save

vv_push_master_conf() in config.php: finds all remote HOST* entries,
resolves Tailscale IPs, SCPs master.conf to each.
rawconf.php calls it after a successful write when file=master.conf.
Scheduler save button shows sync status: "✓ Saved · synced to HOST2"
or "✓ Saved · push failed: HOST2" on error.

Also fix path bug in partnership_transfer.sh — was SCPing to
appdata root instead of Configurations/.
