* Rework of keyfile download and caching.
* Supports interop
* More modular for better testing and build flavour based behavior adjustments
* More resilient handling of failed downloads
* Preperations for future hourly download and serverside checksums

TODO: Finish unit tests, keycache migration and cache health check

* First batch of unit tests and some fixes for incorrect behavior that the tests surfaced.

* Added unit tests for the KeyCacheRepository

TODO: Tests for downloader and migration.

* Implemented POC for migration old key files.

* Fixed legacy file migration and cleanup, improved logging.

* Added unit tests for legacy key file migration.

* Add fallback for different file hashes in the header.

* Yes kLint, we know it's a long method,
but for this it's better to read it in one block vs jumping to extra methods.

* More linting issues, adjusting project code style prevent a few of these in the future.

* Added missing unit tests for `KeyFileDownloader` and fixed faulty behavior that was noticed during testing.

* CRUD (instrumentation) test for `KeyCacheDatabase`

* Remove unused `FileStorageHelper` and related constants+tests.

* Fix last3Hours unit test in deviceRelease mode, we need to explicitly enable debug for these tests.

* Until we have more information about the hashsum's format in the header, default to `ETag

* Split app config server API from diagnosis key download API,
and reintroduce caching for the app config download.

* Add test to check that the cache is used on flaky connections.

* Code changes based on PR comment, part #1.

* Code fluff, formatting.

* Handle download errors correctly.

* Refactoring:
* Remove unnecessary `currentDate` we always start with the newest date from the servers index.
* Make a specialised class for header validation

* Let legacy cache migration abort early, depending on whether the key dir exists.

* If we can't create the base directory for the key repo, throw an exception.

* Delete cache entry if a download fails.

* Fixed test regression due to refactoring.

* Consolidate staleness check into `getStale`

* Consolidate clean up for failed downloads into the download method.
Added tests to check that we delete the keycache entry if the download fails (which we didn't for hours :O!)

* Because the hour-mode uses caching too, we add an explicit button to the test menu that clears the cache.

* Add comment with reference to ticket regarding follow up on the other headers.

* Move expected storage size per country into a named constant.

* Removed blanked internet connection UI state. New Dev base for pipeline issues

Removed the blanket internet connection status:

Removed the connection state from TracingStatusHelper
Adjusted formatters which use the adjusted TracingStatusHelper
Removed connection logic from various fragments (SettingsTracingFragment, etc.)
Adjusted XML views (Settings Fragment: no connection card, etc.)
Adjusted automated tests that previously included the connection state.
Closes JIRA task EXPOSUREAPP-1572

* Update FormatterSettingsHelperTest.kt

* Update fragment_main.xml

deviceForTesters was still using connection state.

* Update Project.xml

* Update FormatterSettingsHelperTest.kt

* Don't execute the transactions as part of any view scopes.
We don't want to cancel them if the viewscope is cleared.

This commit introduces distinct scopes for each transaction.

* Mock injection helper behavior on existing tests.

* Simplify to one CoroutineScope for all Transaction.
Switch context when awaiting the transaction codeblock to end,
otherwise a cancellation still affects us.

* Add test for timeout

* Remove unused code.

* Expand comment on unexpected test behavior

* Even without actual timeout, runBlockingTest causes flaky test behavior.

For plausible deniability, the test result retrieval after the initial registration (via QR or TeleTAN) needs to be part of the same playbook and not two playbooks executed sequentially. For this, this commit:
- updates the initial registration playbook to fetch the test result instead of a dummy request and returns the registration token as well as the test result
- adds an argument "skipInitialTestResultRefresh" to the SubmissionTestResultFragment to optionally skip the initial test result refresh
- includes the argument "skipInitialTestResultRefresh" when navigating from the QR Code scan or the TeleTAN input screen to the SubmissionTestResultFragment
- adds "updateTestResult" to the SubmissionRepository to be able to set the test result without having to refresh it every time from the server
- updates the SubmissionService to set the test result coming from the initial registration playbook

Automatically enable coroutine debugging in DEBUG and test builds. (#1060) (Spawned by EXPOSUREAPP-2267)

* Automatically enable coroutine debugging in DEBUG and test builds.
CWADebug should be used as abstraction for enabling additional non-production debug features and modes.
In the future we can use this abstraction to enable additional debugging options in productions builds.
Sometimes that's the only way to debug issues that can't be reproduced by developers.

* Fix LINTing
