The exclusion list still named the legacy flat `/api/v1/search/executions`
URL, which no longer exists — the endpoint moved to env-scoped
`/api/v1/environments/{envSlug}/executions/search`. Exact-match Set
lookup never matched, so every UI search POST produced an audit row.
Switch to AntPathMatcher over a pattern list so the dynamic envSlug is
handled correctly.
