feat(api-docs): generate response examples from Go structs; fix SS2022 PSK regen (#4996)

Stop hand-writing OpenAPI response examples, which kept drifting from the real payloads (clients/traffic missing fields, inbounds/list exposing userId which is json:"-", the fictional inbound-443 tag instead of the real in-<port>-<transport> form).

tools/openapigen now emits frontend/src/generated/examples.ts: a per-struct example instance built from type defaults, validate oneof/min bounds, and example: struct tags, with nested-ref expansion and a cycle guard. build-openapi.mjs composes the {success,obj} envelope from it for any endpoint annotated with responseSchema (+ responseSchemaArray for lists); the hand-written response is dropped for those. Service DTOs InboundOption/ApiTokenView/ProbeResultUI are added to the walker.

#4996: client password regeneration now produces a valid Shadowsocks 2022 PSK (correct base64 length per cipher) when an SS2022 inbound is attached, in both the single and bulk client forms; backend surfaces ssMethod on /inbounds/options so the UI can pick the right length.

Also: Swagger UI persists the Authorization token across reloads (persistAuthorization).
