tests: Cover all wellFormed asset errors and small 0 axfer e2e test

[nullun]

When working on #6396 I added a simple test, but this PR should cover every asset types wellFormed errors.

I also added three simple 0 asset e2e tests, to make it easier to notice if anything there changes.

Summary of Changes

Hello @nullun, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the test suite by introducing comprehensive "wellFormed" error checks for various asset transaction types and adding new end-to-end tests to cover edge cases related to zero asset transfers.

Highlights

• Asset Transaction Error Testing: New "TestAxferWellFormedErrors", "TestAcfgWellFormedErrors", and "TestAfrzWellFormedErrors" functions were added in "data/transactions/asset_test.go" to thoroughly test "wellFormed" error conditions for asset transfer, configuration, and freeze transactions, ensuring robust validation.
• Zero Asset Transfer E2E Tests: Three new end-to-end test cases were introduced in "test/scripts/e2e_subs/asset-misc.sh" to specifically validate the behavior of transferring zero units of asset 0, covering scenarios like transfers to self, to another account, and transfers with a close-to address.
