Enhanced Chat Embed Configuration View (#3559)

* Changes Made to Embed Chat Configuration
1. Consolidated multiple configuration functions into a single `defaultThemeConfig` object
2. Added full theme configuration support for both popup and fullpage modes
3. Fixed fullpage chat window sizing to use 100% height and width
4. Improved code formatting and readability

* fix: replace empty customCSS quotes with backticks in theme configuration output

* refactor: improve script output formatting for embed chat code

* Fixed incorrect spacing in React component theme prop string templates.
