Phase 6b: fix dashboard Untitled/WEB bug for transcripts

Two bugs in the Recently Completed table:

1. Title showed "Untitled" for all transcripts because the dashboard
   read documents.book_title (populated by PDF metadata voting) which
   is NULL for transcripts. Fixed by COALESCE(book_title, filename)
   in the SQL query -- falls back to catalogue.filename which holds
   the real video title.

2. Type showed "WEB" for all transcripts because the type CASE
   expression only had web and pdf branches, with web matching any
   http% path -- and transcript paths are PeerTube watch URLs.
   Fixed by adding a transcript branch keyed on catalogue.source =
   stream.echo6.co, evaluated before the web branch.

Also adds badge-transcript CSS (purple) and JS rendering case.
Applied consistently to both the Recently Completed and Sources
table queries.
