refactor: store DecayResetTime via WriteDeltaTime pending the anchored-time port

Browse source 
Delta ticks at full precision instead of clamped whole minutes; the read
guard against LastMoved stays since LastMoved is still minute-rounded.
Swaps to Write/ReadAnchoredTime mechanically once the save-time anchor is
ported. Safe to reshape the v10 payload: no v10 saves exist yet.
