File management pattern

Prototyped in route check

[x] Export to file
[x] Load from file
[ ] Make a copy
[x] Name by scheme reference? Probably not; filename and these fields can be edited at different times. And the naming convention doesn't just seem to be scheme reference/name
[x] Mention the current file in the breadcrumb or similar, and make it easy to go change
[x] Use in the other 2 tools
[ ] Tests
[x] Jumping to the overview page when changing files is a bit sudden
[ ] Handle duplicate names when renaming and importing
[ ] Use proper modals for all warning/confirmation screens
[x] Rethink how the delete interaction creates a new blank file and switches to it, because now "untitled1" is hard to get rid of.
[x] Fix $$Generic warning
[x] Fix redirect on GH pages
[x] Share layout code (and improve it generally)
[x] Consider icon buttons
[x] Make sure to validate when switching files
[x] Include warnings/instructions on the Excel import (what things aren't copied)
[ ] Track creation time
