Description:

Adds Map of Scandinavia. This is highly requested and I'm surprised this map doesnt exist already. The layout is based on the Territorial version.
Land area: 2.47M pixels
Nations: 24, with additional nations totaling to 62.

Please complete the following:

• I have added screenshots for all UI updates
• I process any text displayed to the user through translateText() and I've added it to the en.json file
• I have added relevant tests to the test directory

Poem

Scandinavia rises, coordinate by coordinate,
Nations gather, neatly enumerated.
A manifest shines, translations sing,
The map registry welcomes a new thing.
Northward the game now sails!

In `@map-generator/assets/maps/scandinavia/info.json`:
- Around line 226-228: The map entry named in the scandinavia info data has a
spelling typo, so update the region name from Mecklenberg to Mecklenburg in the
source record that feeds the generated manifest. Make the change in the relevant
map metadata object that includes coordinates and flag, then regenerate the
manifest so the generated output picks up the corrected name.
- Around line 291-293: Correct the misspelled city name in the map data entry so
the location currently labeled "Vitsebysk" is updated to the proper
transliteration "Vitsebsk"; make the same name change in the corresponding
manifest entry as well so both references stay consistent. Locate the affected
record by its coordinates and the existing "name" field, and update any matching
city label in the manifest to the same corrected spelling.
