fix: validate denoise field in isValidRecipe (#1661)

[aaniya22]

Closes #1661

Description

isValidRecipe in src/lib/types.ts was missing validation for the denoise field on EditRecipe. This meant malformed or missing denoise values could pass validation and reach downstream code expecting a boolean. Added a typeof v.denoise !== "boolean" check, following the same pattern as the existing stabilization check.
