feat: add persistent chat history and clear button

- ngOnInit restores conversation from sessionStorage on mount
- saveHistory() persists every message exchange automatically
- clearHistory() resets to welcome message and wipes stored history
- Clear button added to panel header (small, subtle, matches dark theme)
- welcomeMessage getter adapts copy based on enableRealEstate flag
