feat/cleanup report

[zeroXbrock]

Motivation

clean up visual artifacts & bugs in reports

Solution

• cleanup report charts
  • show slot when hovering heatmap
  • remove heatmap idle labels
  • limit number of X-axis rows in Time To Inclusion chart
  • log metrics for batched transactions
    • this normally happens in the RPC client middleware but for batches we don't use that so we have to do it manually in TestScenario
• fix unchecked error in reports (if txs are not found)
• handle bad params in fill_block to prevent panic
• collect metrics for batched eth_sendRawTransaction calls
