feat(sub): modern xray JSON format with unified finalmask editor (#4912)

* feat(sub): add finalmask support to JSON subscriptions

* feat(sub): modern xray JSON format with unified finalmask editor

Drop the legacy JSON subscription format entirely and always emit the
modern xray shape:

- Flatten proxy outbounds (no vnext/servers) for vless/vmess/trojan/
  shadowsocks; hysteria was already flat.
- Express fragment/noise via streamSettings.finalmask instead of the
  legacy direct_out freedom dialer + dialerProxy sockopt.

The global finalmask (tcp/udp masks + quicParams) is stored as a single
setting (subJsonFinalMask) and merged into every generated stream,
replacing the separate subJsonFragment/subJsonNoises/subJsonQuicParams
settings.

Reuse the existing FinalMaskForm (used by inbound/outbound) for the
settings UI via a small bridge component; add a showAll prop so all
TCP/UDP/QUIC sections render for the global case. This supersedes the
hand-rolled Fragment/Noises/quicParams tabs with the full mask editor
(all mask types).

Note: this is a breaking change — JSON subscriptions now require a
recent xray client on the consumer side.

* fix
