fix: customer search & linking fully implemented

- Add ajax_search_wc_customers() – searches user_login, user_email,
  display_name AND first_name/last_name meta so any query returns hits
- Add ajax_unlink_customer() to remove an existing Odoo link
- Replace placeholder Customers tab with two-panel UI:
  Step 1 search WC customers → Step 2 search Odoo partners independently
  (WC email and Odoo email do not need to match)
- Results table shows current link status; inline Link/Unlink actions
  update the row in-place without page reload
- Admin JS fully wired: both search inputs respond to Enter key and button
- Add two-panel layout CSS and results table styles
