fix: apply theme accent color scale and other small tweaks (#1768)

- accent-100-1400 wasn't actually applied to spectrum, only actually
matters in a few components (like checkboxes in lists), as most used
other derived variables
- enable stylelint on css files
- change item list selected border color to match iris-grid selected
border color (e2e item-list-selected-border change)
- manually override spectrum selected border color in lists and tables
to not be hardcoded as blue, instead use accent
- adjusted inactive bg color in light theme
- fix mitre gaps in file list and command history list now that border
is more visible
  fixes small mitre gaps:
