Release 2.9.6: PPTX wizard search + image extraction improvements

- Add Europe PMC search source (free API, life sciences, PMC full-text)
- Fix Europe PMC field mapping: journalInfo.journal.title, firstPublicationDate
- Add PMC-only filter button with live paper count
- Move sort selector to search row; shrink year input (flex:none, no spinners)
- Uniform source checkbox sizing with per-source accent colors
- Exclude preview/ directory from image grid (project-images endpoint)
- Numeric sort for project images (slide1→2→9→10→11)
- Skip PDF figure re-extraction if figure_* files already exist (pdf-extract.ts)
- Preserve img:done state across wizard prep re-runs (savedImgDone)
