fix(deps): use catalog for @clerk/nextjs to resolve GHSA-9qr9-h5gf-34mp

The @cipherstash/nextjs package had @clerk/nextjs pinned to 6.12.9,
which pulled in next@15.5.6 as a transitive dependency. This version
is vulnerable to GHSA-9qr9-h5gf-34mp.

Changed to use catalog:security which resolves to @clerk/nextjs@6.31.2,
ensuring next@15.5.9 is used consistently across the monorepo.
