feat: safety plan button always visible in chat input (#38)

Add subtle shield icon button next to send button in chat input area.
Opens the same 5-field safety plan modal as the crisis overlay button.

- Button: #chat-safety-plan-btn with shield SVG icon
- ARIA: aria-label='Open My Safety Plan', title='My Safety Plan'
- CSS: subtle border, hover/focus blue highlight, 44x44px touch target
- JS: click handler calls loadSafetyPlan(), activates focus trap
- Focus trap: returns focus to chat button when modal closes
- Tests: 10 new tests verifying DOM, ARIA, CSS, JS, accessibility

Acceptance criteria:
1. ✓ Subtle safety plan icon in chat input area (always visible)
2. ✓ Opens same 5-field safety plan modal
3. ✓ Does NOT require crisis detection
4. ✓ Keyboard navigable (focus trap, return focus), screen reader friendly (aria-label)
