feat(chat-overlay): add ChatBox config UI + schema persistence

- Elements panel config UI for ChatBox source (font size slider,
  font/member/super-chat/background color inputs, max messages slider,
  timestamp/badge toggles)
- Schema migration: 8 new ChatBox columns on Source table (ChatFontSize,
  ChatFontColor, ChatBackgroundColor, ChatMaxMessages, ChatShowTimestamps,
  ChatShowBadges, ChatMemberColor, ChatSuperChatColor)
- Load/save: Source SELECT and INSERT now include all ChatBox fields
- IsElementsPanelEmpty excludes ChatBox so hint doesn't cover config
- ChatBoxRenderer.cs created: WPF FormattedText + RenderTargetBitmap
  renderer for on-stream chat overlay
- Slider bindings set to TwoWay for live propagation
