fix(game): restore the original plunger launch

Start each ball at the recovered right-lane coordinates and charge the
plunger while Down is held, firing only on release. Render all eleven frames
of resource 901, preserve object 25 as the returning-ball catch, and use the
object table's center-contact extents without adding the art radius twice.

Test Plan:
- cargo fmt --all -- --check
- cargo test
- cargo clippy --all-targets --all-features -- -D warnings
- runtime smoke: start, hold Down, release, and inspect the right shooter lane
