docs: Transport, TransportFactory, HttpClient now use MaybeSendSync (whatsapp-rust#795)

[jlucaso1]

Summary

Follows oxidezap/whatsapp-rust#795, which changed the supertrait of Transport, TransportFactory, and HttpClient from Send + Sync to MaybeSendSync — enabling !Send implementations on wasm32 (e.g. browser WebSocket / fetch handles) while keeping native behaviour identical.

• api/transport.mdx — update Transport and TransportFactory trait signatures to show the MaybeSendSync supertrait and #[cfg_attr]-gated async_trait; add <Note> callouts explaining the wasm/native split; update Best Practices item 1 to reflect that Send + Sync is native-only.
• api/http-client.mdx — same treatment for the HttpClient trait definition.
• changelog/2026-06-09.mdx — add a "Networking traits wasm portability (#795)" entry alongside the existing EncHandler wasm entry.

Test plan

• Verify trait code blocks in api/transport.mdx and api/http-client.mdx show MaybeSendSync and cfg_attr gates
• Verify <Note> callouts appear after each trait definition
• Verify Best Practices item 1 in api/transport.mdx no longer says "must be Send + Sync" unconditionally
• Verify changelog entry links to PR #795 and appears after the EncHandler (#793) entry
