- Add file:// URL handling to AssetFilesInterface in kernel.cpp
- Update home.lua to use file:// prefix for absolute filesystem paths
- Add file:// URL handling to desktop file interface for consistency
This fixes RmlUi stripping the leading slash from absolute paths
when resolving img src URLs relative to the document base.

- Register sandbox APIs (timer, JSON, crypto, VFS) into RmlUi's Lua state
- Add switchAppSandbox() function for context switching between apps
- Update goHome() to reset sandbox context when returning home
- Fix icon loading for third-party apps (handle full paths vs relative)
- Mirror changes between Android service (kernel.cpp) and desktop designer
This enables third-party apps to use sandbox APIs when running in RmlUi.
