[Game] Animate life counter manipulation (#7100)

* Add animations toggles for the life counter and battlefield

Per-effect toggles plus Enable/Disable-all buttons: a life-counter
flash on loss and a crimson battlefield shimmer on damage.


Took 24 seconds

* Animate life changes with a counter flash and battlefield shimmer

- Life loss/gain pulses the player life counter with a brief flash
- The battlefield table zone shimmers crimson on damage
- Respects the per-effect animation toggles

Both effects drive their decay from GameScene's shared animation timer
through the IAnimatedItem interface (QElapsedTimer based), instead of
owning per-item QTimers.

Took 8 minutes

* Revert unintentional cherry picks

Took 2 minutes

* Lambda to re-use path calculation.
