fix(purchases): persist verbose log toggle, fix dropdown stacking, wire Add to Library button

- Verbose capture toggle now persists to localStorage across sessions
- PurchasesView dropdown menus now have mutual exclusion (opening one closes others)
- Add to Library button wired to v2_library_add_folder with download destination tracking
- Added i18n keys for add-to-library success/error toasts (all 4 locales)
