implement website share functionality using share table

- Add support for multiple share URLs per website with server-generated slugs
- Create shares API endpoint for listing and creating website shares
- Add SharesTable, ShareEditButton, ShareDeleteButton components
- Move share management to website settings, remove header share button
- Remove shareId from website update API (now uses separate share table)
