Explorer: add (quick) filter options

[Rikkie82]

Summary

💡 Would be nice to add filter option in explorer (transactions) to filter on moonlight / phoenix only and then also on the types like stake/convert/transfer + the status of transactions (e.g. quickly find failed ones) and e.g. on search on date/ timestamp next to block / tx + add options to quickly find blocks with high amount of TX

Possible solution design or implementation
