# - Restores /luci-static/bootstrap as the active theme
# - Clears /tmp/luci-cache and the WG apply state directory
# - Restarts rpcd + uhttpd only. Does NOT touch network / firewall / Wi-Fi / WG / VXLAN.
# - Does NOT call opkg update or fetch anything from the network. Bootstrap is
#   already part of the v46 image; we only flip mediaurlbase to it.
