test: add regression tests for overlay focus fix (#69)

The crisis overlay was calling overlayDismissBtn.focus() while the
button was disabled during the 10-second countdown. Disabled buttons
cannot receive focus, leaving keyboard and assistive-technology users
without a valid focus target at the most critical interruption point.

Changes:
- Focus the Call 988 link (always enabled) on overlay open
- Add Escape key dismiss handler (refs #95)
- Add focus recovery if focus escapes the overlay
- Add regression tests for initial focus, Escape, and focus recovery
