DRY up ZodError → FieldError mapping
Five journal API route handlers had the same inline lambda:

    parsed.error.issues.map((i) => ({
      field: i.path.join("."),
      message: i.message,
    }))

Pull it into `zodIssuesToFieldErrors(error)` next to FieldError in
`@trails-cool/api/errors.ts` and re-export it so all five handlers
share the same implementation. The path-flattening rule now lives in
one place, and new routes get it for free.

Public error-response shape is unchanged.
