Update dependencies and reestructure build scripts

Restructured the build file based on a new blank Flutter project.
Also removed Gradle version catalogs due to the aforementioned changes.

Updated the following dependencies:

Flutter SDK: 3.13.9 -> 3.16.8
http: 1.1.0 -> 1.2.0
meta: 1.9.1 -> 1.10.0
package_info_plus: 4.2.0 -> 5.0.1
path_provider: 2.1.1 -> 2.1.2
url_launcher: 6.2.1 -> 6.2.3
