Filament drying suggestions

Here are some suggestions for how to improve the filament drying function (in my opinion):
- Make it so that after you dry a roll of filament you don't have to prepare again to dry another spool
- The toolhead should not move so far to the left-back corner because it might crash during homing (the toolhead moves left and backwards during homing just in case the toolhead is right at the right-front corner)
- Add custom presets with customizable names (e.g. for specialty filaments or unique materials)
- Maybe add a bar or some indicator which has a visual indicator as to the amount of time remaining? (not necessary)

General stuff:
- Add status icons to the top section of the screen
- Clock (probably hard to implement)

Hope some of these get implemented!

Start by locating the filament drying function and the top section of the screen in the Python code. Review how homing, spool preparation, presets, and status display currently work. Done means the requested drying workflow, safer homing behavior, custom presets, and any agreed status indicators are implemented and verified.
