fix: resolve npm ci peer dependency conflicts from major bump PR #516

[Copilot]

• actionError.ts: map ZodIssue to ErrorMessage shape instead of casting
• images/operations.ts: use new Uint8Array(avifBuffer) instead of as unknown as Uint8Array
• Validation.ts errors at lines 170/173: fix parse.error.issues mapping for ErrorMessage[]
• Validation.ts errors at lines 224/230: PureTsTypeOfSchema<T, true> changed to z.infer<ReturnType<ReturnType<typeof z.object<T>>["partial"]>> — still mismatching $InferObjectOutput vs output<ReturnType<...>> due to Zod v4 overload resolution
• serviceOperation.ts type predicate: changed expectedArgsArePresent return from ServiceOperationExecuteArgs<'SAFE'> to Omit<ArgsAuthGetterAndOwnershipCheck<...>, 'prisma'> — but { ...args, prisma } still carries the original unknown intersection, so lines 407/423/437 still error
• articleSections/implement.ts, articles/implement.ts, visibility/implement.ts: changed authorizer and ownedXxx parameter types to Omit<ArgsAuthGetterAndOwnershipCheck<false, z.ZodTypeAny, z.ZodTypeAny, ImplementationParamsSchema>, 'params' | 'data'> — but z.ZodTypeAny resolves to ZodType<unknown,...> which TypeScript treats as non-trivially assignable from the concrete Omit<..., 'data'> args passed in
