Replace demo data with 2026 R&D planning, fix zoom and dimension-aware creation

Seeder: Replace 12 demo projects with 6 real 2026 projects from Planning PPTX:
- BRIDGE (Pilot Klundert), CRISP (Compressor Aanbesteding), WISE (Monsternamekast),
  Gemaal 3.0, Afvlakkingsregeling, Structuur & Borging
- 4 strategic themes: Architectuur, Productiewaardig, Lab, Governance
- Real team members, commitments, documents, and dependencies

MetroCanvas: Fix zoom-out scaling
- Wider transition range (0.6→0.25 instead of 0.5→0.1) for smoother feel
- Animated zoom reset on dimension commit (400ms ease) instead of jarring snap
- Guard against re-entry during transitions with isCommitting flag
- Expose dimension metadata (parentEntityType/Id/Name) for parent components

FloatingActions: Dimension-aware creation
- Shows "Nieuw commitment/document" when inside a project dimension
- Shows "Nieuw project/thema" at root level
- Receives depth and parentEntityType props from MetroMap

MetroMap: Wire dimension tracking
- Tracks canvasDepth/canvasDimension from MetroCanvas dimension-change events
- Updates breadcrumb for both page-level and canvas-level navigation
- Passes dimension context to FloatingActions and CommitmentForm

MapDataService: Add parent metadata to buildProjectChildren output
