apps should be able to specify if they want wifi to be disabled when entering them

apps should be able to specify if they want wifi to be disabled when entering them to have more system resources.

should prob be set in toml, perhaps a 3-way false/null/true with false/true disabling/enabling wifi (and if enabling, connecting to configured wifi network) when getting in, and if null just leaving state as is, default being null.

can probably be implemented in Application on_enter/on_exit?
