Use vnext/users structure for VLESS outbound

Replace the previous flat settings map for VLESS outbound with a vnext/users structure. Encryption is now pulled from inbound settings into the user object, a level field (8) is added, and client id and flow are preserved. Address and port are nested under vnext and outbound.Settings is set to {vnext: [...]}, aligning the outbound format with the expected VLESS schema.
