maziggy afa0ba0dc0 Nest projects under a master project and roll their figures up (#1264)
Projects were flat. The parent_id column and the sub-project list existed
but nothing could set a parent outside the API, and a master project's
stats only ever covered its own prints.

The project dialog gets a parent picker, and a project with sub-projects
gets a second card covering the whole tree -- jobs, parts, time, filament,
cost, and progress against every target in the tree added together. That
card is separate from the project's own stats, which keep their existing
meaning; widening them would have restated the figures of anyone who had
already nested projects over the API. Each listed sub-project carries its
own branch's roll-up, so the rows add up to the card above them.

On the Projects page a sub-project is drawn inside its parent's group
rather than as another card in the grid -- two cards columns apart cannot
show that they belong together, whatever the caption says. A sub-project
whose parent the status filter has hidden stays put and names its parent
instead.

compute_project_stats now goes through the same grouped aggregation as the
roll-up rather than its own copy of the SQL, since the two must agree.

Three things the interface made reachable:

- PATCH refused only a project as its own direct parent, so A -> B -> A
  was two calls away. A cycle has no root to roll up to, and the walk
  keeps its seen-set for databases that already contain one.
- A sub-project's percentage was completed quantities against the plate
  target, disagreeing with the page it linked to.
- Deleting a mid-tree project orphaned its children at top level; they
  now move up to its own parent.
