feat: add ICA message decoding and visualization

Add support for decoding and displaying Interchain Account (ICA) messages:

- Decode all 3 ICA message types: CALLS, COMMITMENT, REVEAL
- Detect ICA messages by checking sender/recipient against known ICA routers
- Compute derived ICA addresses using the SDK
- Fetch CCIP Read ISM URLs for REVEAL messages
- Link related COMMITMENT and REVEAL messages bidirectionally
- Add IcaDetailsCard component with:
  - Status sections (delivered/pending) with commitment hash
  - Owner, Account, ISM, Salt, User fields
  - CCIP Read Gateway info for pending REVEAL messages
  - Call details with execution status
- Update debugger to use new ICA decoding API
