Add runtime resource loading and fix Docker incremental builds

Browse source 
- Build images.tar.gz bitmap archive for KiCad icons
- Fetch resources at runtime via HTTP instead of bundling in WASM
- Write to Emscripten virtual FS at compile-time KICAD_DATA path
- Fix rsync timestamp handling for correct make change detection
- Update kicad submodule with WASM settings manager fix
