ui: full IdeaRowActions with disabled-rules + tooltips (M12 T-508)

components/ideas/idea-row-actions.tsx — replaces T-507 placeholder:
- Grill Me: disabled in GRILLING/PLANNING/PLANNED, requires
  product-with-repo + connectedWorkers > 0; tooltip shows specific reason
  ("Grill loopt al", "Idee heeft een product met repo nodig", "Geen
  Claude-worker actief")
- Make Plan: enabled only in GRILLED/PLAN_FAILED/PLAN_READY; same
  prerequisites as Grill
- Materialiseer: enabled only in PLAN_READY (no worker needed — synchrone
  server-side parser); confirm-dialog before action; navigates to product
  backlog PBI anchor on success
- *_FAILED: dedicated "Probeer opnieuw" rotate-icon button
- PLANNED: replaces all three with "Bekijk {PBI-code}" link + open-detail
- Demo: every mutating button wrapped in DemoTooltip with disabled state
- connectedWorkers read directly via useSoloStore (per M12 grill-keuze 16)

Tests: 546/546 still green.

 //
-// Voor nu: alleen een "Open" link en een Archive-knop, zodat de lijst

+//   Materialiseer: alleen in PLAN_READY (geen worker nodig — synchrone parser)
