Close expedition/run seam on combat loss & flee

Run-loss paths (turn-based elite/boss death + flee, exploration combat
death/retreat, interrupt/patrol death) abandoned the zone run but left
the wrapping expedition row at status='active', so the ambient ticker
kept DMing about a dungeon the player had walked away from.

Adds forceExtractExpeditionForRunLoss helper and wires it into every
run-loss site; ambient ticker also skips when the expedition's run is
no longer active as a safety net.
