Arnas Donauskas ddf15184c8 fix(migration-014): drop subquery from buttons CHECK (Postgres disallows it) ... Postgres rejects CHECK constraints that contain subqueries with SQLSTATE 0A000 — `NOT EXISTS (SELECT 1 FROM jsonb_array_elements(...))` inside CHECK is illegal even though it parses. Move per-element validation entirely to the API layer (the upcoming template-validators in PR 3). The DB CHECK keeps the cheap shape guard: NULL or an array of length <= 10. Per-element validation needs specific error messages anyway ("button #3 has no `text` field") which API-layer validators do much better than a CHECK violation.
