Adds Balkhash map: Pipe map

[RickD004]

Description:

High Fidelity use for Impassable Terrain: Lake Balkhash https://en.wikipedia.org/wiki/Lake_Balkhash in Kazakhstan

This map is shaped like a folded pipe, with a 90° curve in the left side, to follow the shape of the lake.
This provides interesting gameplay since players could use the impassable to their advantage, building bases in strategic points where certain enemies cannot hit them with bombs thanks to said terrain.

Various towns and cities from the area as nations. Also historical entities as additional nations with their own new flags

Please complete the following:

• I have added screenshots for all UI updates
• [x[ 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

Balkhash arrives with flags held high,
Nations gather beneath its sky.
Coordinates settle, names align,
A thumbnail glows in WebP shine.
The map registry makes room—
A new adventure starts to bloom.
