Version 1.1.0

This v1.1.0 release modernizes the project for compatibility with the latest version of Flutter, five years after its initial creation. The most significant change is the addition of Web support, making the app available as a Progressive Web App (PWA), while iOS support has been removed to simplify the project.

To round out the project, this update also adds key documentation with a README and LICENSE file, and refreshes the app's metadata and icons for a more consistent experience.
