ci(audit): ignore RUSTSEC-2026-0459, unlinked libsqlite3-sys advisory

The advisory covers bundled SQLite in libsqlite3-sys 0.30.1, which sits in
Cargo.lock only because sqlx resolves sqlx-sqlite unconditionally. sqlx builds
postgres-only, so the bundled C source is never compiled or linked. The fix
needs libsqlite3-sys >= 0.39 but sqlx-sqlite 0.8.6 pins ^0.30.1; the waiver is
documented to retire if the sqlite feature ever enters the build.
