feat: update loading shares of table

[luka-nextcloud]

Update access control for viewing table shares and improves the user interface logic to ensure only authorized users can load share information.

• The index method in ShareController.php now requires MANAGE permission instead of READ to access table shares, ensuring only users with management rights can view share information.

• The indexView method in ShareController.php now requires MANAGE permission instead of READ to access view shares, ensuring only users with management rights can view share information.

• In Dashboard.vue, the loadShares method now checks if the user can manage the table before loading its shares, preventing unauthorized users from accessing share data.
