fix: add persistent safety plan button in chat header (#38)

Add a subtle safety plan button in the always-visible 988 banner header
so users can access their safety plan mid-conversation without requiring
crisis detection to be active.

- Button with document SVG icon, always visible in header
- Keyboard navigable with focus outline (blue, consistent with banner)
- Opens same 5-field safety plan modal
- Existing footer and crisis panel buttons preserved
