[EVM] Avoid approvals with native pointers

[stevenlanders]

Describe your changes and provide context

• native pointer shouldn't manipulate any state because sei-side transactions won't inform it
• native coins don't support approve / transferFrom, so logically neither can the pointer

  Testing performed to validate your change

• unit tests
• integration tests

looks good! in the call, we discussed potentially updating the symbol/name to pull from the token itself - is that something we still wanna do?

I initially updated it, but then looked further at the deployment process, and there's some validation to prevent deployment if these metadata items do not exist but still allow a governance proposal registration (scenario is a native coin without metadata, which allows one to specify metadata during this deploy)

Closing for now, we believe approvals on EVM side only are okay because they enable Uniswap and other EVM-friendly situations.
