fix(game): restore effect-seven special respawn

Track required effect-seven state through active multiball and implement 1000:ae6e's final single-ball respawn at record 148 without consuming a player marker. Preserve velocity, clear required state, and hold the 0875-style record-148 gate until a broadphase-active type-four record reenables it.

Test Plan:
- cargo test --all-targets
- cargo clippy --all-targets --all-features -- -D warnings
- rumdl check CHANGELOG.md RECONSTRUCTION.md README.md
- git diff --check

 ### Fixed
 
+- Restore `1000:ae6e`'s required-ball special respawn: armed or completed
+  effect-seven play grants one final `(17,23)/(0,3040)` ball without consuming
+  a marker, clears required state, and suppresses record 148 until the next
+  broadphase-active type-4 record reenables it.
 - Replace the invented post-move `y>470` fallback with the original pre-scan
   prediction bounds `x<=0 || x>340000 || y<=0 || y>460000`, including
   one-slot removal during multiball and next-substep handling after a response.
