Input defaults to type="string" #541

• Where: Input's default type: in input.rb, and date_picker.rb's
  input_attrs (type: "string"). Snapshot date_picker/without_label.
• Effect: string is not an HTML input type; browsers fall back to
  text, so nothing breaks, but the attribute is invalid and will be
  flagged by any validator, including Herb's.
• Fix: type: "text" in both places; re-record (on the 2.0 line) input/*,
  date_picker/* and whatever else changes.

Surfaced by the golden HTML suite (PR #536), which pins what 1.6 renders today — this defect included. Per maintainer decision (2026-09-19) main stays as is: this is addressed on the 2.0 line, and the golden snapshot that pins it is re-recorded there with the diff reviewed.
