🚀 WireGuard Multi-Client, Panel Accessibility, Balancer Observatory & Hardened Settings

• 🔐 WireGuard goes multi-client — WireGuard inbounds are now first-class multi-client (native users), with a reworked client-config UX, a collapsible config card, configurable DNS, and client IPs allocated inside the existing peer subnet.
• ♿ Panel accessibility — screen-reader and keyboard accessibility were brought across the whole panel.
• ⚖️ Balancer Observatory — a tabbed Observatory / Burst Observatory form, validation that defers errors until a field is touched or saved, and a burst observer for random/roundRobin strategies with a fallbackTag.
• 🛡️ Hardened settings & restore — sensitive setting changes now require re-confirming 2FA, and the database-restore body-cap exemption was tightened.
• 🛰️ REALITY target scanner — a live REALITY target scanner with IP/CIDR discovery.
• 🧪 Dev channel from stable — opt into the rolling dev channel directly from a stable build.
• 🔗 Subscription & inbound polish — Host VLESS Route baked into subscription UUIDs, {{EMAIL}} shown on the first sub-body link only, a remark template applied to Export all inbound links, and legacy externalProxy converted to hosts on import.
• 🧰 Dev toolchain & deps — a canonical Makefile, golangci-lint v2, plus Ant Design 6.5 and xray-core v26.6.27.

ℹ️ Heads-up: WireGuard inbounds are now natively multi-client — existing single-peer inbounds migrate automatically to the clients model. The minimum eligible Xray version was raised (bundled core bumped to xray-core v26.6.27); update any custom cores accordingly. With 2FA enabled, sensitive setting changes now prompt for a fresh 2FA confirmation before they apply.
