fix(profiles): Snapmaker U1 — add bed dimensions to fdm_U1 for all nozzle variants (#14391)

fix(profiles): add printable_area to fdm_U1 so all nozzle variants inherit correct 270x270 bed

The 0.2/0.6/0.8 nozzle profiles inherit from fdm_U1 which had no
printable_area defined, causing them to fall back to a smaller default
bed size. The 0.4 profile was the only one that set it explicitly.

Move printable_area and printable_height to the shared parent (fdm_U1)
so all Snapmaker U1 nozzle variants get the correct 270x270mm bed.
Bump vendor version to trigger profile re-sync on existing installs.
