Resolve degrades gracefully when BGG_API_TOKEN is missing

A 401 on an uncached title no longer aborts the run: cached titles
resolve and save, blocked titles are listed with registration/token
instructions and left out of matches.csv so a future run picks them
up untouched. Supports the take-photos-now, resolve-later workflow.
