fix: add missing phase-transition overlay element (closes #101)

Bug 2 of 3 from #101: showPhaseTransition() looked for #phase-transition
but the element didn't exist in index.html. Phase transitions silently
failed — no celebratory overlay appeared on phase-up.

Added:
- Overlay div with .pt-phase, .pt-name, .pt-desc children
- CSS for centered fullscreen overlay with fade transition
- Matches the dark theme + gold/blue accent palette

Note: Bugs 1 (toast text) and 3 (mute/contrast buttons) were already
fixed in previous commits.
