♻️ Rename app.graph.project to app.graph.projection

`project` is a Penpot noun: a team holds projects and a project holds
files, and the graph will carry a `Project` node table. A namespace
called `app.graph.project.document` therefore reads as "the graph of a
Penpot project" and means the opposite.

`projection` is the word the rest of the subsystem already uses for the
operation: `projection-data`, `load-projection!`, `:projection` in the
ingest report, and `app.graph.schema.projection`.

Pure rename. Both namespaces and every alias move; nothing else changes.
