Mirrors web/html/form/stream/stream_finalmask.html as a shared
FinalMaskForm component used by both modals — they share the same
StreamSettings shape (addTcpMask/addUdpMask/finalmask/enableQuicParams)
so a single template handles both. Surfaces:
- TCP masks for raw/tcp/httpupgrade/ws/grpc/xhttp networks: fragment,
sudoku, and header-custom (with the 2D clients/servers groups, each
row supporting array/str/hex/base64 packets and a randomize button
for base64).
- UDP masks for hysteria protocol or kcp network: hysteria gets just
salamander; kcp gets the full type list (mkcp variants, header-*,
xdns/xicmp, header-custom with flat client/server lists, and noise).
Switching to xdns shrinks the kcp MTU to 900 to match the legacy
panel's behavior.
- QUIC Params for hysteria or xhttp: congestion (incl. brutal up/down
fields), debug, UDP hop ports/interval, idle/keepalive timeouts,
path-MTU discovery toggle, and the four receive-window tunables.
