funman300 8719f77ec2 fix(engine): regenerate table backgrounds to flat Terminal palette ...

The post-Option-D screenshot showed Terminal cards correctly but
a green felt play surface — the chrome migration only retuned
in-engine constants, leaving the on-disk PNGs at
assets/backgrounds/bg_*.png as the legacy felt textures.

Adds solitaire_engine/examples/background_generator.rs following
the same regeneratable pattern as card_face_generator. Five solid
near-black variants from the base16-eighties palette:

- bg_0: #151515 (Terminal canonical, BG_PRIMARY)
- bg_1: #0a0a0a (BG_DEEPEST)
- bg_2: #1a1a1a (BG_ELEVATED — same as card face)
- bg_3: #121820 (slight cool tint)
- bg_4: #201812 (slight warm tint)

Per design-system.md the Terminal play surface is *flat* — no
felt, no gradient — so all 5 slots are pure solid colours. Each
PNG is 120 × 168 (matches the legacy tile size; spawn_background
stretches to window_size * 2.0 at runtime so source resolution
is immaterial). On-disk weight drops from ~16KB average to ~100
bytes per tile.

Run with: cargo run --example background_generator --release
