webOS: a TV app with the views of arr-tui

A TypeScript web app for LG webOS TVs (webOS 5 / Chromium 68 and newer),
driven by the remote: Movies and Series search with the Trakt lists,
Library with status, title and file-property filters and download marks,
seasons and episodes, release search and grab, Downloads, Calendar,
Settings and Log. It talks to Radarr, Sonarr, SABnzbd and Trakt directly
(they answer cross-origin requests); the arr-tui config is baked in at
build time and can be changed on the TV.

dev/screenshots/server.py answers cross-origin requests and accepts writes
for it; webos/dev/drive.mjs drives the app in Chromium for screenshots.
