feat: initial WooDoo plugin – WooCommerce & Odoo 19 integration

- Odoo JSON-RPC client (no Composer, uses wp_remote_post)
- Admin settings page under WooCommerce with connection test
- Customer linking: search Odoo partners from WP user profile
- My Account: Odoo Invoices tab with PDF proxy download
- My Account: Book a Meeting tab (slot calculator + calendar.event)
- WC order → Odoo sale.order auto-sync on processing status
- Products matched by SKU; partner auto-created from billing info
- Uninstall cleanup (options, user meta, order meta, DB table)
