fix(ui): restore original high-score windows

Replace modern overlays with the reconstructed HighScore child and DIALOG 32514 topology, exact DAT993 background, row coordinates, original strings, unpadded scores, and 21-character edit behavior. Restore OK/Cancel semantics, including Escape preserving the prefilled name and allowing an accepted empty name, with deterministic screenshot scenarios.

Test Plan:
- cargo test --all-targets
- cargo clippy --all-targets --all-features -- -D warnings
- rumdl check CHANGELOG.md RECONSTRUCTION.md README.md
- cargo run --quiet -- --simulate highscores --step 0 --screenshot /tmp/tdkpin-highscores.png
- cargo run --quiet -- --simulate name-entry --step 0 --screenshot /tmp/tdkpin-name-entry.png
- git diff --check
