Fix element stacking during partial layout

Elements (text, dynamics) were stacking on top of each other after edits,
only returning to correct positions after save/reload. This occurred because
partial layout reset only affected the edited measure range while skyline
collision detection processed entire systems, creating mixed stale/fresh data.

Changes:
- Enable position reset in LayoutData::reset() to force clean recalculation
- Reset autoplace state to ensure proper collision detection
- Expand PassResetLayoutData to reset all measures in affected systems,
  not just the edited range

Fixes the mismatch between partial reset scope and full system processing.
