feat(admin-web): skill zip import and folder-grouped role picker

- parse skill package zips client-side, mirroring backend ingestion limits (ADR-0018)
- add zip upload flow on skills page and zip replace in SkillEditor
- group role skill bindings by the shared management folder tree (ADR-0028)
- add fflate dependency
