Fleet op timer ui update

Created by: iAddz

-reuses the design from structure timers (past&future timers) -changed sort to place the most recent/closest timers at the top

idk how controversial it'll be but I removed the Location & Details column headers. line members know their formup location in a system 99% of the time, fc's are too lazy to fill them out, it makes the table look uggo

• unused code removal
