# Description
When using the Bambu H2D, users can use Filament Grouping, a button found next to the bed preview. When not on a H2D profile, the button is hidden. However, it remained usable, and clicking an empty space below all the buttons causes the dialog to appear.
This PR fixes that by adding a check before the button is registered.
Addresses point 9 (focusing on the 2nd bullet) in #12684
## Tests
Tried to click on the empty area right below the column of buttons (see the below images)
Made sure to have the H2D profile loaded as well, and checked that the dialog still opens for that printer.

# Description
When creating a new filament preset and setting the Printer Dependencies to "All", the preset does not save this setting. This issue only occurs on creation due to code that is meant to validate the data to prevent a case where the filament is compatible with none of the printers.
EDIT: While I considered redoing the data validation for this tab overall, I have now preserved the original purpose of the code, which is to add the current printer as a compatible printer only if:
- the base preset is a System preset
- the user has not specified any compatible printers
Notably, this seems to be the cause of #11959
Moving the data validation from `Preset::save_current_preset` to `Tab::save_preset` allows the Preset function to be simplified through removal of the current printer parameter.
# Screenshots/Recordings/Graphs
There is no visible change on the UI.
## Tests
Tested the following combinations of filament presets:
- System->new User
- User->new User
- User->same User
Tried to set them to All, where the System->new User should be the only case where this is replaced by a default.
In any case where there are printers already set, those settings should be kept.
* Fix: GCodeViewer displaying inconsistent data in title and body
* Fix: remove actual flow info from GCodeViewer title
* Refactor: reduce repetition of N/A and headers
