Mirror the rewritten documentation into the wiki
Every page now matches the docs in the releases repo at 0.6.347, with
the same 41 screenshots (tokens and URLs masked). New pages: Reactive
Overlays and Thons. Stream Tools is split across Stats, Polls,
Predictions, and Thons, Channel Points, Moderation, OBS Control, Video
Manager, and Closed Captions. Event Sources, Goals and Charity, LuckyBot
Cloud, and Spotify are refreshed for the current connections and
features. Home follows the README, and a sidebar lists every page.
Bring wiki up to date with the current app: rewrite Settings (new connections, TTS providers, System tab detail), add Stats and Captions pages, fix Chat/Channel Points/Polls and Predictions/OBS Control/Video Manager/Overlays/Advanced Editor/Widgets/Goals and Charity/Moderation gaps
Reframe docs around no Streamer.bot; update remaining pages
Event Sources now states every Twitch feature works without Streamer.bot
(watch streaks and Power-Ups are native), and lists what Streamer.bot is
still optionally for. Updated Visual Editor (keyframe animator), Advanced
Editor (LUCKYBOT API with BEACON alias), Activity Feed (events from any
source, not just Streamer.bot), and finished the Beacon to LuckyBot rename.
