feat(quotesdb): add Yew/Wasm UI dependencies to Cargo.toml

- Add yew 0.22 with csr feature for Rust/Wasm SPA frontend
- Add yew-router 0.19 for client-side routing
- Add gloo 0.11 for Web API utilities (timers, fetch, events)
- Add wasm-bindgen 0.2 matching Nix wasm-bindgen-cli 0.2.108
- Add wasm-bindgen-futures 0.4 for async fetch support
- Add web-sys 0.3 for raw DOM/browser API bindings
All UI deps scoped to wasm32 cfg target to avoid host build pollution

Closes ticket 93515e
