✨ feat(settings-announcements): improve editor UX with modal & tooltips

* Added “Expand Edit” button with `Maximize2` icon to open a large modal editor
* Introduced full-screen `TextArea` modal; content syncs back to main form via Form API
* Switched to correct `TextArea` import from Semi UI to fix invalid element error
* Implemented ellipsis & `Tooltip` for “content” and “extra” columns to keep table concise
* Added state management (`showContentModal`, `formApiRef`) and related handlers
* Updated success messages & punctuation for consistency
