Step 8 of the Vue→React migration. Ports the xray config entry: page shell,
basics/routing/outbounds/balancers/dns tabs, the rule + balancer + dns server
+ dns presets + warp + nord modals, the protocol-aware outbound form, and the
shared FinalMaskForm (TCP/UDP masks + QUIC params). Adds useXraySetting that
mirrors the legacy two-way sync between the JSON template string and the
parsed templateSettings tree. The outbound model itself stays in JS so the
class-driven form keeps its existing mutation API; instance access is typed
loosely inside the form to match.
The shared FinalMaskForm.vue and JsonEditor.vue stay alongside the new .tsx
versions until step 9 — InboundFormModal.vue still imports them.
Adds react-hooks/immutability and react-hooks/refs to the already-disabled
react-compiler rule set; both flag the outbound form's instance-mutation
pattern that doesn't run through useState.
