Prayer Progress released mid-start no longer reports a failed map

Browse source 
Prayer Progress is a heavy gallery tab: switching away empties its slot. If the map
is still starting, initializeMap returns silently (useMapInstance's liveness
checks) and leaves map.value null. onMounted then logged "[doxa-simple-map] Map
failed to initialize, check token and container": a console error that blamed
the token for a tab switch.

Measured on development's tip, served from its committed tree, on the shared
browser, a phone in Arabic (pp-fastswitch.mjs): switched away 150 and 500 ms after
selecting the tab, 2 runs in 10 logged it. The control runs, switched away after a
full start or never switched away, logged nothing.

Same shape as the research map's quiet cancel (0c263fb60): when the map's
container is gone or detached, both failure paths return quietly. A mounted pane
that really fails still logs.
