Swapping Archery Range Sprites

[pazam-h2]

In the Knight town, the current Archery Range visuals feel reversed thematically.

Archers wear red, while Rangers, their upgraded version, wear blue.
However, the current town building sprites shows the opposite: the upgraded Archery Range is red, while the unupgraded Archery Range is blue.

I suggest swapping the visuals so that:

Archery Range uses the currently upgraded/red-looking sprite.
Upg. Archery Range uses the currently unupgraded/blue-looking sprite.

This would make the building progression better match the units it produces:

Red building → Archers
Blue building → Rangers
