fix(BaseInputV3): static label click issue

[Nil0ofar]

This resolves the issue where clicking the floating label did not focus the input when an explicit id was passed.

• Ensure 'for' attribute always matches the id.
• Compute inputId from explicit id if provided, otherwise fallback to name.
• Prevent id override of the name attribute.
• Added unit tests to cover:
  • default id behavior
  • explicit id behavior
  • label association with input id
  • name preservation when id is provided
