test(common): fix and improve Ethereum proof tests

[lumtis]

Description

Fix the current unit test failure we have

The reason for the failure was to use Ankr RPC for Goerli for unit test and this endpoint is no longer supported.

We already add an issue to remove use of RPC so this PR replace the RPC usage with static data fetched from Sepolia network.

Some other improvement:

• Remove logs: not necessary as unit test are easy to debug
• Simplify the test for the essential
• Add more assertion, previous tests show errors in logs but didn't assert for it

Some other tests related to MsgBlockHeader and add trackers don't work when not relying on the RPC. The implementation of sample.Header was also incorrect.
Since block headers are not yet ready to production in any case, I commented out some of the tests and track it here: #1875
Future tests should mock proof verification

Closes: #1458 #1871
