refactor: update zod imports to version 4 and adjust error handling

- Changed all zod imports from "zod" to "zod/v4" across multiple files.
- Updated error handling in forms to use new zod error configuration.
- Refactored custom error mapping to align with zod v4 changes.
- Adjusted password validation logic to utilize new zod features.
- Cleaned up unused locale error mapping code.
- Enhanced type definitions for async iterables in zod utility functions.
