Explorer improvements/follow-up

• Searching a block height shouldn't look for all the hashes that contain the block height, but instead I'd suggest searching for height only if the input is a number and less than the current max height (which we have access to, right?), and if the number is higher, we search for hashes

• Can we add the blocks view in the dashboard under the summaries? Kinda like https://etherscan.io/

• It would be cool if we could click on block hashes on the dashboard and get to the block's page right away

• For the transactions table inside the blocks view - can we use the same tick for the status that we use in the transaction detail page? Also, for failing transactions, lets display a x or something in red, while just adding the status message in the same column. I suspect most transactions to be successful, so the status message column would be mostly empty and it'd probably look better merged into one column.

• How hard is it to make the dashboard title and slogan configurable for users?

• Eventually, we should figure out if we want to display hashes as either hex or base64

• Also, we need to make a starter-kit PR to add the missing tasks to the module config
