Two independent grids, each with a size and a snap toggle:
- Garden grid (owner-set, in the garden settings form): drives the
editor's visual grid and, when snapping is on, snaps objects on
place/move and snaps their dimensions to whole grid steps on resize.
- Bed grid (per plantable object, in the bed Inspector): when snapping
is on, plants snap to the bed's grid on place/move, and the grid is
drawn inside the focused bed. Plant radius stays free.
Snapping defaults off on both, so existing gardens keep free placement.
Grid spacing shares the [1cm, 100m] range and defaults to 1m (garden) /
30cm (bed); 0 is treated as unset and re-defaulted.
Backend: migration 0005 adds grid_size_cm/snap_to_grid to gardens and
garden_objects, threaded through domain/store/service/api with service +
api round-trip tests. Frontend: new geometry snap helpers (unit-tested),
schema/type plumbing, canvas + overlay snapping, and the two forms.
