feat: Support configurable priority colors

Improve accessibility and UX by giving administrators an option to
configure the colors used for issue priorities on the dashboard. This
allows admins to choose colors according to their issue priority order
and the need of their team members.

Furthermore, enhance accessibility by giving overdue issues a distinct
shape too, not only color. This ensures that users with color vision
deficiencies can easily identify overdue issues on the dashboard.

The colors can be chosen from a palette of 10 colors with 5 shades each,
so that themes can adjust these colors e.g. for dark mode, high
contrast, or matching the theme better. All colors are defined as CSS
variables, and chosen based on a oklch color palette for visual
distinction.

Note: This is first feature that heavily patches into Redmine's core and
requires a database migration. This will need some serious testing and
feedback to ensure it works well across different Redmine versions and
setups, including other plugins.

Closes #802
