feat(statics): add Go Account (OFC) support for MegaETH tokens

- Add ofcMegaethErc20 factory function with addressCoin='megaeth'
- Add tofcMegaethErc20 factory function with addressCoin='tmegaeth'
- Update existing OFC tokens to use correct factory functions
- Add OFC equivalent for test token (ofctmegaeth:tmt)
