jaeone94 df42b7a2a8 fix: collapsed node connection link positions (#10641)
## Summary

Fix connection links rendering at wrong positions when nodes are
collapsed in Vue nodes mode.

## Changes

- **What**: Fall back to `clientPosToCanvasPos` for collapsed node slot
positioning since DOM-relative scale derivation is invalid when layout
store preserves expanded size. Clear stale `cachedOffset` on collapse
and defer sync when canvas is not yet initialized.
- 3 unit tests for collapsed node slot sync fallback
(clientPosToCanvasPos, cachedOffset clearing, canvas-not-initialized
deferral)
- 3 E2E tests for collapsed node link positions (within bounds, after
position change, after expand recovery)

## Review Focus

- `clientPosToCanvasPos` fallback is safe for collapsed nodes because
collapse is user-initiated (no loading-time transform desync risk that
#9121 originally fixed)
- `cachedOffset` clearing prevents stale expanded-state offsets during
collapsed node drag
- Regression from #9121 (DOM-relative scale) combined with #9680
(collapsed node ResizeObserver skip)
