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

 Use `--step N` instead of `--at SECONDS` to reproduce one exact update. The
 available scenarios are `loading`, `attract`, `highscores`, `name-entry`,
-`autoplay`, `launcher`, `flippers`, `panel`, `targets`, `claw-1`, `claw-6`,
+`effect-7`, `autoplay`, `launcher`, `flippers`, `panel`, `targets`, `claw-1`, `claw-6`,
 `claw-7`, and `claw-18`; `--seed N` fixes random choices.
 `autoplay` charges each ball and operates the flippers from live ball position
 for long end-to-end validation runs.
