fix(e2e): remove invalid 'always' signal type from CRD

The previous attempt to add a default catch-all decision used type="always"
which is not a valid signal condition type. Valid types are only: keyword,
embedding, domain.

Root cause analysis reveals a deeper issue: PII E2E tests use model="MoM"
which triggers domain classification, but the test data is domain-agnostic
(contains PII like SSN, names without domain context), so no domain matches,
no decision is selected, and PII detection is disabled.

This is a fundamental test design issue that requires discussion.
