Inbound, ClientRecord, and InboundClientIps store settings /
streamSettings / sniffing / reverse / ips as JSON-text in the DB. The
API was passing that text through verbatim, so every consumer had to
JSON.parse a string inside a string. Add MarshalJSON / UnmarshalJSON so
the wire format is a real nested object, while still accepting the
legacy escaped-string shape on write. Frontend dbinbound.js gets a
matching coerceInboundJsonField helper for the same dual-shape read
path, and inbound.js toJson stops emitting empty/placeholder fields
(externalProxy [], sniffing destOverride when disabled, etc.) so the
new normalised JSON stays terse. api-docs and the inbound-clone path
are updated to the new shape. Controller route lists are regrouped so
all GETs sit above POSTs.

UI stores v1 and v2 both as "hysteria" with settings.version, but
inbounds that came in from imports / manual SQL can carry the
literal "hysteria2" string and get silently dropped everywhere we
switch on protocol.
Add Hysteria2 constant + IsHysteria helper, use it in the places
that gate on protocol (sub SQL, getLink, genHysteriaLink, clash
buildProxy, json gen, inbound.go validation, xray AddUser).
Existing "hysteria" inbounds are untouched.
