featu: add Khalani integration

[nicosampler]

This PR adds Khalani integration and depends on hyperlane-xyz/hyperlane-monorepo#5845.

The core logic was added here.

Khalani has a particular flow to complete a transfer:

1. An approval for the ERC20
2. A deposit to a smart contract denominated assetReserves

For both of these actions, warpCore.getTransferRemoteTxs is used, ensuring the existing flow works as it does for warpRoutes.

After these two actions are completed, Khalani requires a few extra steps to complete the transfer. The current implementation does not cover these, so a new condition was added for this special case. When the token standard is Khalani, a new block of code was added that enables us to:

3. Fetch intent-quota, which provides transfer stats.
4. Request an EIP712 signature, signing the intent-quota from step 3.
5. Wait for mTokens (mirror tokens on Khalani's Arcadia chain) to be minted.
6. Send the intent to Khalani's API, called Medusa.
7. Wait for the network of solvers to solve the intent.

It was also necessary to adapt the transaction store and modal to request the user signature and also to reflect the progress of the transaction.
