Android app: Help (?) should use the instance's marketing URL on self-hosted instances

Response (via Google Gemini): Your observation is 100% correct. The Cause: While the web client dynamically builds help routes from endpoints.marketing, the Android client currently has the help URL hardcoded (e.g., 'https://help.fluxer.app/') instead of consuming the instance's bootstrap/well-known config. Instance/Admin Settings: There is currently no setting in /admin or server-side configuration that can resolve this, as the mobile app simply does not use the marketing endpoint for that button action. Resolution: This requires an upstream fix in the mobile client repository to bind the ? action to endpoints.marketing + '/help' with the official URL as a fallback.
