docs: Revamp README and add APK naming convention
This commit introduces a complete overhaul of the `README.md` to improve project presentation. Key changes include:
* Adds a new header with the app icon and a Google Play badge.
* Updates the feature graphic and includes a note distinguishing the OSS version from the Play Store version.
* Refines the "Open Source Libraries" section to be more structured.
* Moves the main preview image into the `docs` directory.
Additionally, the `app/build.gradle.kts` file is updated to configure a standardized naming convention for output APK files, including flavor, version, and build type.
* refactor copyright headers and fix README icon alignment
This commit introduces two main changes across the codebase:
The `spotless/copyright.kt` template have been updated for consistency:
* The author name is simplified from "Episteme Authors" to "Episteme".
* The contact email prefix is shortened from "Electronic mail:" to "mail:".
Second, the `README.md` file is adjusted to correct the vertical alignment of the app icon with the project title.
