## Description:
Closes https://github.com/openfrontio/OpenFrontIO/issues/1619.
On capture, defense posts will be downgraded.
On the live version this means defense posts will be destroyed, as
defense posts can only be level 1.
Misc. changes:
- added `decreaserLevel` helper
- cleaned up if/else in tick unit loop for clarity to avoid yet another
nested layer
Continuation of the stale PR,
https://github.com/openfrontio/OpenFrontIO/pull/1622.
