fix(ui): restore effect and player display assets

Load and render DAT400-407 effect panels with the preserved wheel overlap, and add deterministic effect-7 coverage. Restore exact 1008:0996/0b9e score fields, configured-player rows, current/status indicators, signed status thresholds, and six 5x5 per-player ball-marker slots.

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 effect-7 --step 0 --screenshot /tmp/tdkpin-effect7.png
- cargo run --quiet -- --simulate launcher --step 0 --screenshot /tmp/tdkpin-display.png
- git diff --check
