Do a performance audit of the interface
As kclock is a utility application and is likely used for short periods of time, special attention needs to be made to make it as fast and fluid as possible.
Do an audit by looking through all of the kclock interface code, and apply suggestions from https://doc.qt.io/qt-5/qtquick-performance.html
Main goals:
- Reduce start time to within 0-3 seconds on the PinePhone
- Reduce time for loading of alarm new/edit page
- Have spinners if it is impossible to make components load instantly
- Load components in async so it does not freeze the application
