propresenter-now-next module: Now/Next tile fed by propresenter-core

Milestone 4. propresenter-core copied in unchanged (single home for every
ProPresenter 7/20 quirk). Server part owns the one polling connection and
exposes GET /state plus GET /stream (SSE, change-detected, heartbeated);
health reported for the admin page. Client ports the wall display's
rendering: fill-the-box title fit that never breaks words, tidied titles,
slide meta + progress bar, NEXT list with hidden-row '+ N more' overflow,
playlist name and live chip, all scaled to the tile via a JS-set --unit.
Verified against pp-mock.js including the arrangement-repeat case (the
counter follows core's honest-live-index rule, never X > Y) and
kill-and-restart recovery.
