actions/ideas.ts already lists PLAN_READY in GRILL_TRIGGERABLE_FROM,
but lib/idea-status.ts ALLOWED_TRANSITIONS was missing the
PLAN_READY → GRILLING edge. As a result, clicking Grill on a PLAN_READY
idea returned 422 "Status-transitie ongeldig" while the UI button was
enabled. Mirrors the existing PLANNED → GRILLING re-grill behaviour.
- lib/idea-status.ts: PLAN_READY allows GRILLING in addition to
PLANNING/PLANNED
- __tests__/lib/idea-status.test.ts: explicit assert for
PLAN_READY → GRILLING and PLAN_READY added to the regrill loop
covering every GRILL_TRIGGERABLE_FROM status
