[RFE] Allow techs to mothball units with partial time

[PhoenixHeart512]

Enhancement Type *

New Feature

Brief Description of Enhancement *

My request is that if you use a tech to mothball a unit that is already doing maintenance, have them only use the time they have available for the mothballing task, similar to how Refits are currently handled. If you have a tech start a refit that doesn't have the full 480 minutes available, the tech only uses their unused time for the refit but continues to maintain their assigned unit(s).

Use Cases or Rationale

Currently, if you mothball a unit using a tech assigned to maintenance, the tech stops doing their maintenance until the mothballing is complete. This results in the next maintenance cycle having a "partially maintained" penalty.
