chore!(sdk-coin-celo): remove unused files and functions

BREAKING CHANGES:
* Removed modules/sdk-coin-celo/src/lib/types.ts - entire file deleted
* Removed deserialize() function from modules/sdk-coin-celo/src/lib/utils.ts
* Removed dependencies: @celo/connect, @celo/contractkit, @celo/wallet-base, @celo/wallet-local, ethers

These components were unused and removing them reduces bundle size and dependency overhead. If you were importing these directly, you'll need to use alternative implementations.
