feat(shirabe): resolve advisory instanceof TODOs via AnySecurityAdvisory

Add an Ignored variant to the advisory enum (renamed to AnySecurityAdvisory)
so the PHP three-class hierarchy PartialSecurityAdvisory -> SecurityAdvisory
-> IgnoredSecurityAdvisory maps one-to-one onto enum variants.

Replace the hard-coded auditor downcasts with as_security_advisory()
(PHP `instanceof SecurityAdvisory`, true for both full and ignored) and
as_ignored(), implementing severity/cve/source ignore filtering, the
toIgnoredAdvisory conversion, and the table/plain row output faithfully.
