Route CRUD:
- Create route with name, description, optional GPX upload
- Route detail page with stats (distance, elevation), version history
- Edit route (name, description, upload new GPX → creates new version)
- Delete route with confirmation dialog
- Route list page sorted by last updated
GPX handling:
- Import: parse GPX, compute distance/elevation stats on save
- Export: download route GPX as file
- Version history: new version created on each GPX update
