Jeff Emmett ff45193ba2 feat: Grey out stale locations, remove indoor map, dedupe pings 
1. Stale locations (>5 min old) are now greyed out on the map with
   reduced opacity and hover tooltip showing time since last seen
2. Removed indoor map button and related UI elements
3. Location request pings now deduplicate by participant name to
   avoid pinging the same user multiple times
