Main Blockscout page banner height bug fix and new changes/New tooltips for Block Details page added/ Token image added to the Token instance page.

[YegorSan]

Issues introduced at :

• Add tooltips to the "Block Details" page #1771
• ERC-721 token instance page #2541
• This issue wasn't introduced yet :
  Fixed height issue with top-banner on the main Blockscout page.

Motivation

• Add tooltips to the "Block Details" page #1771 - New Tooltips were needed for the Block Details page.
• ERC-721 token instance page #2541 - ERC-721 token instance page required some changes. I've added a new block with the image into the Total Supply container. As content is rendering dynamically - we still must add some additional logic for Total Supply container ( if token type ERC721 => return new created div with image and hide text info). As for tabs - still need similar logical solution ( if token type ERC721 => hide unnecessary tabs from the page).
• Top banner on the Blockscout home page is opening with the height bug now. I've added several changes in order to fix this issue (fixed height etc.) .

Changelog

Enhancements

• Add tooltips to the "Block Details" page #1771 - Added tooltips for the Block Details Page (Additional logic is required for Miner/Validator tooltip text and Block Rewards container. ) :
  

• ERC-721 token instance page #2541 - Added new container with the ERC721 token image, which should be rendered only if token type is ERC721. (Additional logic is required).

Additional Note

Please let me know how to create a new entry to CHANGELOG.md with current PR correctly . I've made a reset of some commits in my local forked repo - as I've accidentally pushed some unnecessary changes . So based on the foregoing info - this latest commit is including multiple changes inside. Next time i will make each commit separately, sorry for my mistake.
