Changes in ZBX-23760 make it impossible to remove discovery checks if they are used in conditions of discovery actions. At the same time, when editing a discovery rule, removing and then adding a check back results in an error that this discovery check is used by an action. To prevent this and improve the user experience as such, it is proposed to make the following changes to the list of checks in the discovery configuration form:

• The "Remove" button should be disabled if a discovery check is used in action conditions.
• A help icon with action names or action count (similar to Users > Authentication > LDAP settings > Servers > User groups) should be displayed next to the name to make it clear where or in how many actions this particular discovery check is used.
