fix(game): restore physical target-bank rules

Attach recovered score and rule flags to type-2 collision records. Deactivate
complete three-line groups through their contact owner, rearm all five
bumper-value groups after completion, and rearm all four central groups after
advancing the TDK diamond.

Remove the broad side and colored-target coordinate checks those physical
records replace. Preserve exact 5,000, 100,000, bank, and wheel-trigger scores
from the initialized object ledger.

Test Plan:
- `cargo test --all-targets` -- 46 passed
- `cargo clippy --all-targets -- -D warnings` -- passed
- `cargo build --profile production` -- passed
- target-bank deactivation, completion, and rearm test -- passed
- `git diff --cached --check` -- passed
