feat: make Detail scrollable and zoomable

[vvvyyynet]

When user scrolls or zooms (=ctrl.+scroll) on Details table the selected window will adapt in Details as well as in Brush.

Main changes:

• add wheel-listener in Details
• remove brushE and replace with let selection = $state({start:number, end:number})
• refactor some hardcoded defaults into an external Devilstable_DEFAULTS.json
• change behavior of brush.move() in Brush, which now reacts to selection

Further changes and comments

• I hope I got the typing right.
• Of course, one could define the DEFAULTS in Devilstable.svelte, but I think it is cleaner to import from the .json instead of passing props.
• I refactored or commented a few more things -> see the comments in the individual commits.

This PR is kind of the wrong way round... I'm trying to fix this by pushing the changes you made onto https://github.com/DHBern/presentation_parzival/tree/32-devilstable-make-detail-scrollable then reset main to where it was (forcefully) and then create a new PR in the right direction. :-)
