feat: replace Bandsintown with Ticketmaster for concert events

Backend: swap /api/events/:artist to use Ticketmaster Discovery API
(startDateTime=now, classificationName=music, size=20, sort by date).
Maps TM response to the same {datetime, venue, offers} shape the modal
expects. Returns [] if TICKETMASTER_API_KEY is not set.

Frontend: remove all debug console.logs from events.js; drop redundant
client-side date filter (TM already filters by startDateTime server-side).
