fix(frontend): stabilize generated schema snapshots

[gokugiant]

Summary

• normalize set-like locks and manipulates arrays before writing blok.json
• prevent Python hash-seed-dependent ordering from causing false codegen drift
• regenerate the committed frontend schema snapshot and state bindings

Verification

• yarn build
• yarn types
• repeated codegen in the same backend process
• codegen after restarting the backend with a different PYTHONHASHSEED
• yarn prettier --check plugins/generate-app.ts
• git diff --check

Note

The full frontend lint command still reports the pre-existing react-hooks/set-state-in-effect error in src/lib/auth/AuthProvider.tsx; it is unrelated to this change.
