Implement the flagged object-84 selector and initially inactive type-4 object
149. Choose a different effect from 1-6, render the enabled target from its
original active-table rectangle, award its static 500 points, then apply the
recovered bonus or cashout action and disable it until reselected.
This replaces the final unimplemented help-screen target effect with its
original dispatcher values.
Test Plan:
- `cargo test --all-targets` -- 49 passed
- `cargo clippy --all-targets -- -D warnings` -- passed
- `cargo build --profile production` -- passed
- live object-84 probe activated record 149 and selected effect 3
- effect selection/consumption test -- passed
- `git diff --cached --check` -- passed
