fix: resolve Tauri full build TypeScript errors from tauri-typegen

- Consolidate ws-state and cert-tofu emit calls in ws_proxy.rs into
  private helper functions (emit_ws_state, emit_cert_tofu). One call
  site per event name prevents tauri-typegen 0.5.0 from generating
  duplicate event listener functions.
- Add CI fixup step that injects 'export type Value = unknown' into
  generated types.ts — tauri-typegen cannot map serde_json::Value to
  a TypeScript type, so the generated file references an undefined type.
