docs: stop describing verdande as "Todoist Pro"

Claiming to be Todoist Pro is both inaccurate and an invitation to a
trademark complaint. Describe verdande on its own terms — a fast,
self-hosted task manager — and keep the Todoist references to what they
factually are: import/export interop, and a filter grammar close enough
that people coming from there already know it.
