feat(tour): use icon descriptions matching actual UI elements

Update input area tour step to describe each icon with visual hints that
match the actual Lucide icons used in the input area. Also update
TourStep component to properly render newlines as line breaks so the
bulleted list of icons displays correctly.

Icons now described:
- Pencil (✎) for expanded prompt editor
- Image (🖼) for file attachments
- History (⏱) for session history toggle
- Eye (👁) for read-only mode
- Brain (🧠) for extended thinking
- Keyboard (⌨) for submit hotkey toggle
