Summary by cubic

Add proper disabled-state support for DatePicker (single and range), MultiSelect, Tags, and RadioButton so they ignore input and show disabled styles. Backend now sends the disabled flag for DatePicker to keep UI in sync.

• Bug Fixes
  • DatePicker: prevent popover opening for single and range when disabled; stop range updates; add cursor-not-allowed on trigger.
  • MultiSelect: ignore key actions when disabled; disable tag remove buttons; add disabled cursors to input and badges.
  • RadioButtonGroup: add disabled prop; pass to RadioGroup and RadioGroupItem.
  • Tags: block tag removal and input when disabled; add disabled styles and cursors.
  • Backend: include disabled in DatePicker.to_dict so the frontend respects it.

<violation number="1" location="frontend/src/components/ChatSettings/DatePickerInput.tsx:102">
P2: Disabling while the popover is open can leave it stuck open because `onOpenChange` is removed (and range mode ignores close events), so the controlled `open` state can no longer be updated to `false`. This results in a disabled field still showing an interactive popover (Reset/Confirm remain active).</violation>
