fix: sketches on planes built from the model can project, intersect, include and hold text (#459)

Project, Intersect, Include 3D Geometry and Text resolved the active sketch's
plane without the model, so on a construction plane that is built from geometry
(perpendicular to a plane through a sketch line, through three points, midway
between two faces, tangent, along a path) they stopped with "this plane is built
from the model: evaluate first". Evaluation resolves the same plane against the
model before the sketch, in its component's frame; the sketch commands now do
the same, in one place, for adding a link, refreshing the links on an edit,
snapping a point onto an edge and the internal face profiles.

Tests: a sketch on a plane through a sloped sketch line projects a point and a
line of that sketch, follows a parameter that tilts the plane (also after reopen
and after another edit), holds text, intersects a body and includes an edge; the
same on a three-point plane and a midplane.

 Run from a script or the control channel, every command that adds sketch geometry returns the
 ids of what it added (`created: {points, curves, constraints, dimensions}`). Ids are stable and
 never reused within a sketch, even after a delete, so a script can dimension or constrain the new
