[refactor] Improve renderer domain organization (#5552)

* [refactor] Improve renderer architecture organization

Building on PR #5388, this refines the renderer domain structure:

**Key improvements:**
- Group all transform utilities in `transform/` subdirectory for better cohesion
- Move canvas state to dedicated `renderer/core/canvas/` domain
- Consolidate coordinate system logic (TransformPane, useTransformState, sync utilities)

**File organization:**
- `renderer/core/canvas/canvasStore.ts` (was `stores/graphStore.ts`)
- `renderer/core/layout/transform/` contains all coordinate system utilities
- Transform sync utilities co-located with core transform logic

This creates clearer domain boundaries and groups related functionality
while building on the foundation established in PR #5388.

* fix: Clean up linter-modified files

* Fix import paths and clean up unused imports after rebase

- Update all remaining @/stores/graphStore references to @/renderer/core/canvas/canvasStore
- Remove unused imports from selection toolbox components
- All tests pass, only reka-ui upstream issue remains in typecheck
