feat: add OWL product mapping UI with live AJAX search

- AjaxSearch component: debounced 300ms, calls /woo/search/* endpoints via rpc()
- ProductMapping client action: 3 tabs (Mapped, Unmatched, Conflicts)
  - Mapped tab: live search, bulk unmap/sync, per-row price/inventory sync toggles
  - Unmatched tab: split Odoo|WC panels, click-to-select, Map/Create/Ignore actions
  - Conflicts tab: Use Odoo / Use WC per-row and bulk resolve
- Top bar: instance selector, Fetch Products, Sync Now, live stats
- woo_dashboard.xml updated with ir.actions.client records
- woo_menus.xml pointed at new client action
- CSS: full layout styles, badges, split view, progress bar, buttons
