feat: add ActivityPolicy for MachineAccount resources (#563)

## Summary

- Adds `config/milo/activity/policies/machineaccount-policy.yaml` with
an `ActivityPolicy` for `iam.miloapis.com/MachineAccount`
- Covers create, delete, deactivate, activate, and generic update audit
rules
- State-specific rules (`deactivate`/`activate`) match on `spec.state`
to produce meaningful summaries for activation state changes
- No event rules — the controller sets conditions but does not emit
Kubernetes Events
- Follows the same `config/milo/activity/` convention established in the
dns-operator repo

## Test plan

- [ ] Apply to staging with `kubectl apply -k config/milo/activity/` (or
wire into the Flux Kustomization)
- [ ] Verify policy is `Ready=True` via `datumctl get activitypolicies`
- [ ] Create a MachineAccount and confirm an activity entry appears
- [ ] Update `spec.state` to `Inactive` and confirm "deactivated"
activity appears
- [ ] Update `spec.state` back to `Active` and confirm "reactivated"
activity appears
- [ ] Delete a MachineAccount and confirm a delete activity appears
