Commit Message

feat(common): add error format option to validation pipe

Add a new `errorFormat` option to `ValidationPipeOptions` that allows
users to choose between two validation error formats:

- 'list' (default): Returns an array of error message strings with
  parent path prepended to messages (current behavior)
- 'grouped': Returns an object with property paths as keys and arrays
  of unmodified constraint messages as values

The 'grouped' format separates property paths from error messages,
which prevents custom validation messages from being modified with
parent path prefixes.

Closes #16268
