fix: crisis overlay focuses enabled Call 988 link instead of disabled button (closes #69)

The crisis overlay's showOverlay() was calling overlayDismissBtn.focus()
immediately after setting overlayDismissBtn.disabled = true. Disabled
elements cannot receive focus in browsers, so the overlay opened without
a valid keyboard focus target.

Changes:
- Focus the .overlay-call (Call 988 link) on overlay open — it's always
  enabled and the most important action for a user in crisis
- Move overlayDismissBtn.focus() to the countdown completion handler —
  the button focus now fires when it becomes enabled
- All existing tests pass (139 passed)
