Feature: show transactions in block details

[pk910]

Feature request:
The explorer should be able to show eth transaction details on the block details page.

Current status:
The explorer only displays the transaction count, but no further transaction details.
Technically the signed transactions are available for post-bellatrix blocks without adding further complexity by calling a EL RPC.
However, they're not yet decoded or visualized.

I think it'd be great to get some basic details (hash, from/to addr, amount, & call data) displayed for each transaction in the block details.
Further transaction details like receipt information, events, internal transactions or tx traces should not be included for the first implementation.
Showing that stuff would need some EL RPC interaction, which introduces additional complexity that might not be worth adding.

Decoding the transactions should be easy: example

I think that's a good first issue for anyone who wants to join development for this explorer :)
Anyone who contributed to beaconcha.in before will probably feel familiar with the structure of this lightweight explorer ;)
