feat: Deploy Upgradable MSCA contracts and paymaster to Avax (#84)

## Summary

Deployed and verified upgradable MSCA contracts and paymaster contract
to avax and avax-fuji.

## Detail
### Changeset

This pull request adds deployment details for the
`DeploySponsorPaymaster` and `DeploySponsorPaymasterProxy` scripts
across two specific chains. The updates include transaction hashes and
notes that these deployments used `cast send`, so no `run.json` files
were generated.
