fix(flutter): show Junk/TCP-Frag controls only when transport is UoT 

Junk packets and TCP fragmentation only take effect on the UoT (TCP)
transport — the UDP path applies neither — so showing them (with an
implicit "UoT only" caveat) while UDP is selected was misleading. The
whole DPI OBFUSCATION section is now gated on transportMode == 'uot' and
appears/disappears reactively when the Transport dropdown changes
(setDialogState already rebuilds the dialog).
