cosmic-proto without cosmjs (#9691)

refs: #9408

## Description
cosmjs deps add a lot of size and complicates our builds (#9583) At runtime we only need `Decimal` so this vendors that (just the subset necessary) and drops all other runtime deps.

### Security Considerations
less supply chain

### Scaling Considerations
none

### Documentation Considerations
Maybe get this upstream to reduce maintenance.

### Testing Considerations
CI suffices?

### Upgrade Considerations
None, not on chain.
