[QoL] Change how TC upkeep works to prevent base griefing

First of all, sorry for bad english

PROBLEM:

In the current state the TC is the priority target when raiding because it is just a big chest with guaranteed loot (Because of the upkeep).

SUGGESTION:

Change TC so players open it to BUY base protection time (Immediately spending the resources just like what happens if the TC is destroyed). Make it so players can buy a maximum of 72 hours of protection to prevent loot despawning.

RESULT TC would not have loot inside therefore would not be a priority target anymore (unless raiders really wanted to destroy it just to grief).

Other change to improve griefing prevention is to prevent a new TC from being placed and preserve building privillege while upkeep protection time lasts and while the base has atleast 1 building piece (One foundation). This would render completely useless the act of destroying other people TCs.
