fix(wiki): maintain sources.tokens for wikis (sum of page token_counts)

sources.tokens was only set at ingest, so wikis showed no/stale token count on the card (blank wikis showed nothing; converted ones showed the stale original count). rebuild_wiki_directory_structure (called after every wiki mutation) now also sets sources.tokens to the sum of wiki_pages.token_count; blank wiki create sets tokens=0. So the card reflects live wiki content.
