fix(singbox): prevent UDP routing to HTTP outbounds (#45) and improve dashboard metadata

- Ensure selector and urltest groups require all member outbounds to support UDP
- Add explicit reject rule for UDP on non-UDP outbounds to avoid sing-box router log spam
- Add http/s:// to connection URL description in LuCI settings and update localization
- Display transport protocol badges on dashboard outbound cards and modal rows
- Deduplicate and collapse UDP routing error lines in telegram logs and bug report
