refactor(web): convert 6 enums to as-const objects (batch 4)

Convert enum declarations to `as const` objects with companion type aliases
per issue #27998, improving tree-shaking and enabling literal type inference.

Files changed:
- web/app/components/workflow/types.ts: ControlMode, ErrorHandleMode
- web/models/datasets.ts: DatasetPermission, WeightedScoreEnum, RerankingModeEnum, DocumentActionType
