fix(verify): restrict verify tool access to approve_tree and super_pe…

[yasiru98]

Description

• Fixes an issue where users with only the list_tree policy could access the Verify tool.
• In AppContext.js, the hasPermission check for the Verify route included POLICIES.LIST_TREE alongside POLICIES.SUPER_PERMISSION and POLICIES.APPROVE_TREE. Since hasPermission returns true if the user has at least one of the listed policies, list_tree alone was sufficient to gain access.
• Removed POLICIES.LIST_TREE from the Verify route permission check so only users with approve_tree or super_permission can access the tool.
