Load-phase markers: attribute the teal->green minute

Browse Source 
The measured 58s uncontended load has ~0.2s of model loads -- the rest
is unattributed.  Stamp the renderer LoadMission span and count the
CheckLoad passes that find the event queue still busy (each delays the
ready transition by its 1s re-post), so the next live run names the
cost.
