fix(quotesdb): resolve compiler warnings in api and ui

- Remove redundant #![cfg(target_arch="wasm32")] from d1.rs (module
  declaration in mod.rs already gates it)
- Remove unused D1Repository re-export from db/mod.rs
- Drop unused page/total_count fields from UI ListResponse struct
  (only total_pages is consumed by the browse page)
