Fine Performance Metrics: bokeh dashboard overhaul

[crusaderky]

Overhaul the implementation of the Fine Performance Metrics dashboard.

• Closes Bokeh 2.4 is broken in 2023.6.0 #7908
• Closes Fine Performance Metrics: Dashboard glitch randomly adds/removes tasks #7848
• Partially addresses Fine Performance Metrics Dashboard nice-to-haves #7832
• Add y axis to stacked graph
• Add % and total to tooltips
• The tooltips for 'count' no longer show a spurious ".0"
• Use a color pallette with higher contrast
• The color pallette and legend are now aligned between the three plots
• Increase unit test coverage
• Fix bug in stacked graph when switching from bytes to seconds, which would cause the y axis maximum to be stuck at >1 billion (gigabytes) instead of going back to hundreds (seconds)
• Blocks Add spans to Fine Performance Metrics bokeh dashboard #7911

Known issues

• The legend of the stacked graph does not lose hidden activities
• The plot does not refresh as soon as you change a selector
