fix: reset to connect step on reload; add back link to flash step

Browse source 
On page reload the serial port reference is lost. If saved state points
to flash_firmware or later and port is null, drop back to connect_device
so the user can re-select their device.

Also add a small '← Back to Connect' link at the bottom of the flash
step so there is always a visible escape route.
