QDoc: Code cleanup

* Unify members; use s_ or m_ prefix instead of _ suffix.
* Remove unnecessary member that duplicates content in base class.
* Add [[nodiscard]] annotations where applicable.
* Add overloads to virtual methods that have been extended with
  parameters with default values.
* Make single argument ctors explicit.
* Remove semi-colon from namespace declaration.
