improve compact colony report

[zeitlinger]

• show good production in blue (i.e. good) if all required buildings are built (including factories, even if factories are not available yet)
• show bells and hammers, too - this makes it easier to see
  • if all buildings are built (see above)
  • if there is a production warning for hammers - this should have worked by showing underconsumption for lumber, but this was confusing and didn't work
• don't show underconsumption anymore - always show the warning on the good being produced
• it's not a warning anymore if the net production is negative (to make all warnings and alerts actionable)
• add a new column showing workers that are not working
  • this includes persons and excludes expert soldiers, units that are fortified, improving or already have a destination
• add a column showing units that are working, but not working in their profession

Future work

• the warning color is hard to see - I would propose some some yellow (second screenshot), but that's not included in the PR yet
• similarly, the export color is indistinguishable from the alert color for people with red-green weakness, so I've tried out white (second screenshot)
• the trade advisor should probably be changed to align with the new logic (good warnings, colors) - it can probably use the same logic under the hood

Note

• this is a very big PR, partly because I started by extracting methods from the report before making changes
• I can split the PR into multiple PRs if this helps the review process
