feat(admin): redesign GoodsView with dual-tree UX, filter bar, inline CRUD

- Two-line good nodes with country + tag chips, hover tooltip
- Resizable dual-tree with fixed-height panels (no node overlap)
- Filter bar: search, country filter, tag filter (multi-select with rename)
- Mode switch (品类/国家) pushed to right via spacer
- Inline create country/tag in edit & config modals via quick-create buttons
- Right tree node height auto-fix for locate highlight
- Filter dropdown styles in global scope for teleported popper
- Backend: multi-tag (GoodTag junction), goodImage column, origin goods tree API
- Admin response interceptor unwraps {data, success} envelope
- Simplified sidebar to single 商品管理 entry with tabs
- SyncView simplified to product sync only
