Merge develop into main (#348)

## App state

Improved app state management in `LoaderService` and `GuiService`:

- Re-ordered some of the state transitions
- Hardened `GuiService` for repeated events (that might trigger a re-render of an app that's already rendered)
- Validate state transitions in `LoaderService` and crash if an app transitions from the wrong state to the next one.

## LoaderService

- Removed `tt::loader::` functions and expose `LoaderService` interface publicly.
- Implement `stopAll()` and `stopAll(id)` which stops all instances of an app, including any apps that were launched by it.
- Rename `stop()` functions to `stopTop()`
- Created `stopTop(id)` which only stops the top-most app when the app id matches.
- Moved `loader::LoaderEvent` to `loader::LoaderService::Event`
- Changed app instance `std::stack` to `std::vector`

## Improvements

- `ElfApp`: error 22 now shows a hint that `main()` might be missing
- Starting, installing and uninstalling apps now stops any running app (and its children) on the stack

## Bugfixes

- `HttpdReq` out of memory issue now shows an error message and doesn't crash anymore (this would happen on devices without PSRAM with WiFi active, when an app was installed)
- `GuiService::hideApp()` lock should not wait for timeout and now waits indefinitely
- `Buildscript/release-sdk-current.sh` deletes the previous local release before building a new one

## Code correctness

- App classes were made `final`
- Apps that had a `void start()` now have a `LaunchId start()`
- `tt::app::State`: renamed `Started` to `Created` and `Stopped` to `Destroyed` to properly reflect earlier name changes
