Fix LAPPD time alignment plots

[furkan-bilgin]

Describe your changes

This PR rollsback the previously added 2D LAPPD last 100 file time alignment histograms that was removed by pull request #319 due to it being worked on the Application branch of ToolAnalysis, not online_monitoring, as the said 2D plots were introduced in the commit 727ba58 was not present in the main branch.

It also changes the last 1000 file time alignment histogram to 2D as well.
