chore: autoapply detekt (static code analysis and linting)

[anonvt]

Applies Detekt to all projects automatically.
Some notes:

• The top level gradle file serves to basically define the version of the plugin, it still needs to be applied in each subproject in a plugin block
• The configurations in the subProjects block work for setting the Detekt JVM, but not the config file, so they also need to be set in the project's buildfile
• config attribution inside the task name clashes with the config macro in the :app buildfile, so I changed the macro to properites
