[rakanalh]

Description

Dashboard changes should look something like this

Performance

The notification time and bundle extraction logic shows numbers around the following:

2025-09-10T11:23:01.984627Z  INFO citrea_sequencer::runner: Bundle state extraction took 0.137ms
2025-09-10T11:23:02.019260Z  INFO citrea_sequencer::runner: Canonical notification preparation took 0.305ms

Meaning that they will appear as 0 in the "Stacked Sequencer Block Production Flow" histogram
