Allowlist the iplocate DB patterns (add to patterns, not just mutable_patterns)

The iplocate patterns were added to mutable_patterns only, which tags TTL but
does not allowlist — requests 403'd 'access denied'. Verified: existing
mutable_patterns-only paths (branch archives, webadmin) also 403, while patterns
entries (uv) return 200. Add the iplocate patterns to patterns (the allowlist),
keeping them in mutable_patterns so the daily-updated DB stays mutable.
