chore: stage all in-progress work before repo split

Web app: new entities (Image, RenderedAsset, SharedImage, Token, DeviceImageHistory), enums, repositories, controllers, message handlers, migrations, tests, frontend upload/library/sticker UI, Vue components. Firmware: EPD background screen binaries + gen scripts, setup_bg header. Infra: ddev config, test bundle, gitignore coverage dir. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
