Session 102, Step 2: Esc z-index order, split-view buttons, S4 Fix, auto-focus tweaks, removed-issue sync, story deselect, progress bar, session counters, note count/reuse, readiness fix

- AIM-1935 Esc key: close topmost overlay by z-index order across both dialog and output overlays
- AIM-1937 Split-view: updateStoryEditButtons() on focus for both sides' Cancel/Save
- AIM-1958 S4 Fix button: remove broken checkInterval; rely on _onAllClear callback
- AIM-2150 Auto-focus: switch to lastStep on review-results return; skip confirm in nonLastStep; skipPrompt on manual collapse
- AIM-2251 Issues tab sync: Removed/Transitioned → individual section, not resolved list
- AIM-2263 Clear wfLastStory when output file is processed so auto-select picks fresh
- AIM-2265 Project detail: move progress bar below stat boxes
- AIM-2311 Session step counter: treat Removed(7) as canceled not finished
- AIM-2316 Note toggle count excludes consolidated; status btn opens existing note in edit mode with noCollapse
- AIM-2317 initWfReadiness: replace hasTestResult with statusId !== NotImplemented
