[Bug] Remove nonexistent vesting precompile address

## Type

- [x] Bug
- [ ] Feature
- [ ] Proposal / Discussion

## Summary

`0x0000000000000000000000000000000000000803` is included in the active static precompile defaults, but cosmos/evm does not implement or register a vesting precompile.

## Reproduction (for bugs)

1. Inspect `AvailableStaticPrecompiles`.
2. Observe that the vesting precompile address is included.
3. Inspect `DefaultStaticPrecompiles`.
4. Observe that no vesting precompile implementation is registered.

## Impact

The default params and local genesis scripts can mark a nonexistent static precompile as active. This may cause calls to that address to hit the missing registered precompile path.
