Why keyid_manage_list needs a policy

This tool modifies email filtering configuration by adding or removing allowlist/blocklist entries. These changes are reversible (entries can be added back or removed), making it a Write operation rather than Destructive. The severity is medium because misconfiguration could redirect or filter legitimate emails, cause email loss, or enable spam/phishing, but the effects are recoverable.

From the tool's definition Tool description: 'Add or remove entries from allowlist/blocklist for inbound/outbound filtering.' The verbs 'add' and 'remove' indicate write operations that create or modify filter rules.
