Routes saved in the Fly App's mission library now sync to a new per-user
routes collection on the API Server, in the WaypointMissionSpec JSON
format. The library pulls on load and pushes on every save and delete,
merges last-writer-wins by updatedAt, keeps unacknowledged deletes as
tombstones, and keeps working offline. Each signed-in account has its
own copy on the device; routes saved while signed out go to the first
account that signs in.
The API Server gets list / get / upsert / delete route endpoints with a
PocketBase migration, and the Web App a read-only Routes view on the
dashboard (rebuilt dist).
Tested against a fake PocketBase and a fake server only; not yet tried
with a real sign-in on the tablet.
