Decode warp route messages

[yorhodes]

Problem

• Warp route messages are opaque on the explorer

Solution

• Leverage https://github.com/hyperlane-xyz/hyperlane-monorepo/pull/3784 to decode message bodies for warp route messages

User story:

For users in the Explorer, see warp route data: which token, the amount of it, and the fees paid.

Nice to Have

• [ ] Fetch warp route from registry and render additional metadata (eg collateral token metadata, chains connected, etc?)
