Add the printable 48-Hour Fast Start sheet

/fast-start: one-page checklist that personalizes with the member's
ID, invite link, and a scannable QR of /join/<id> when opened from
their dashboard (or with ?id=). Print stylesheet flips it to clean
black-on-white letter format; floating translate/chat widgets are
now excluded from printing on every page. Dashboard share card
links to it; chatbot + AI prompt synced.
