Update wg_manager.sh

	CHANGE: Flow Cache is no longer auto-disabled for ANY router model (previously two models:RT-AX86U/RT-AX58U were EXPLICITLY hard-coded to DISABLE Flow Cache); instead users must now EXPLICITLY uncomment DISABLE_FLOW_CACHE directive using command 'vx'
CHANGE: When all 'client' Peers have been stopped, ensure Flow Cache is ENABLED
CHANGE: WebUI Beta v0.15 now uses 'checkboxes' rather than 'radio' buttons as the listed configuration settings items are not mutually exclusive.
CHANGE: WebUI Beta v0.15 'Connected' checkbox (which displays the state of the 'client' Peer) is also an active button and can toggle (stop/start) the 'client' Peer if clicked.
