## Summary
This PR:
1. fixes a deserialization mismatch for macOS automation permissions in
approval payloads by making core parsing accept both supported wire
shapes for bundle IDs.
2. added `#[serde(default)]` to `MacOsSeatbeltProfileExtensions` so
omitted fields deserialize to secure defaults.
## Why this change is needed
`MacOsAutomationPermission` uses `#[serde(try_from =
"MacOsAutomationPermissionDe")]`, so deserialization is controlled by
`MacOsAutomationPermissionDe`. After we aligned v2
`additionalPermissions.macos.automations` to the core shape, approval
payloads started including `{ "bundle_ids": [...] }` in some paths.
`MacOsAutomationPermissionDe` previously accepted only `"none" | "all"`
or a plain array, so object-shaped bundle IDs failed with `data did not
match any variant of untagged enum MacOsAutomationPermissionDe`. This
change restores compatibility by accepting both forms while preserving
existing normalization behavior (trim values and map empty bundle lists
to `None`).
