V130: Widen phoenix_kit_annotations_kind_check for the new
"marker" kind.
The Media viewer exposes Etcher's marker (highlighter) tool. A
marker persists like any other shape via annotations-changed, but
it's pure marking — the viewer skips the annotation composer for it,
so it carries no title/comment. Without widening the CHECK constraint
(and the schema's @kinds) the insert is rejected and the marker
silently fails to save across a reload.
Idempotent: each ADD CONSTRAINT is preceded by DROP CONSTRAINT IF EXISTS on the same prefixed table.
