Type mutation inputs with shared Zod schemas instead of Record<string, unknown>

Replaced loose Record<string, unknown> types on useCreateTicket,
useUpdateTicket, useCreateUser, useUpdateUser, useUpdateWebhook,
and useCreateSavedView with their corresponding shared schema types.
Fixed three type errors this surfaced at call sites.
