Error on filter by JSON field with enum values

Description and expected behavior
Error on filter by JSON field with enum values. Easy to understand by looking at the screenshots below.

Screenshots

...
enum BKPType {
  ...
  CAPSTONE
  ...
}
type BKPProposal {
  ...
  bkpType BKPType?
  ...
}
model BKP with Base {
  ...
  Proposal BKPProposal @json
  ...
}

function queryBkps() {
  return db.bKP.findMany({
    where: {
      Proposal: {
        bkpType: "CAPSTONE",
      },
    },
  });
}

But this works (but requires type check bypassing in the zenstack dist code)

function queryBkps() {
  return db.bKP.findMany({
    where: {
      // @ts-expect-error
      Proposal: {
        bkpType: '"CAPSTONE"',
      },
    },
  });
}

Environment:

• ZenStack version: 3.8.3
• Database type: Postgresql
• Node.js/Bun version: Node 26.4.0
• Package manager: pnpm
