Debug pass 3: the snap-tile build
- Removed widget drag-to-resize entirely — dashboard tiles snap to the grid now.
- Resident Manager “Open chart” falls back to a direct profile fetch instead of failing silently on a cache miss.
- Form deletion in the assessment builder (admin-only, and blocked while assessments exist on a form).
- Removed the CareBoard page-level scrollbar — columns scroll internally.
- New dirty-check diagnostic logging across the save pipeline.
- Full test suite green: 68/68 v2-q, 36/36 v2-k.
