[explorer] Sort transactions chronologically

[Maksandre]

Currently, transactions in the block explorer are sorted by a transaction hash: https://explore.nil.foundation/address/00013e10552287291227159daab35ff67567643c/transactions
However, this makes little sense because we care more about recent transactions.

I understand that blocks cannot include a timestamp. However, maybe Block Explorer can store an "estimated timestamp."

Anyway, it would be easier to find needed transactions if they were sorted chronologically.
