fix(zod4): replace deprecated z.interface with z.object (#2214)

Zod v4 dropped z.interface, z.looseInterface, and z.strictInterface.
Updated to use z.object with appropriate modifiers:
- z.interface -> z.object
- z.looseInterface -> z.object().passthrough()
- z.strictInterface -> z.object().strict()

Fixes #2213
