Add folder support in breadcrumb

[ConiKost]

I would like to see, when you do open a route in web planer, that the breadcrumb also does show the full path including folders.

Route is in folder:

After opening, I cannot go back directly to folder, but only back to "root"

So I would like to see something like "Meine Routen / Ausfahrten / Weserbergland / 2026.03.22 Ausfahrt" (like you have it in your storage)
