📚 Improve Aptos Rust SDK Documentation & Keyless Support

[spielcrypto]

📝 Issue Summary

The latest Aptos Rust SDK docs on docs.rs fail to build, leaving no API reference or examples—particularly for keyless account creation. Our team is building a Telegram bot in Rust using Teloxide and relies on keyless flows to generate user accounts without managing private keys.

🔍 Steps to Reproduce

1. Go to https://docs.rs/crate/aptos-sdk/latest/builds
2. Observe the “build failed” indicator and missing content
3. Search the sidebar for “keyless” or AccountClient—nothing appears

✅ Expected Behavior

• Error-free documentation for the aptos-sdk crate on docs.rs
• Keyless API reference, e.g.

  let keyless_client = AccountClient::new_keyless(base_url, auth_token)?;
  let account = keyless_client.create().await?;

• Code snippets demonstrating:
  • Initializing a keyless client
  • Creating a keyless account
  • Signing and submitting transactions
  • Querying account state
• Examples in both high-level and low-level modules, plus integration tests or a playground link

❌ Actual Behavior

• docs.rs reports build failures; no pages are rendered
• No documentation for keyless account flows
• Developers cannot integrate Aptos keyless wallets in Rust projects

🖥️ Environment

• aptos-sdk version: latest on crates.io
• Rust toolchain: stable-x86_64-unknown-linux-gnu
• OS: Manjaro Linux (kernel 6.x)
• Docs host: docs.rs

Actually what I need to do I don't need keyless but anyway it is nice to have
