fix: enable Pay by default and use M3ActionDialog for payment popups

- Enable Pay reaction in DefaultReactionRowItems (was disabled)
- Replace DropdownMenu with M3ActionDialog + M3ActionSection + M3ActionRow
  in both PayReaction (reactions row) and PaymentButtonWithTargets (profile),
  matching the style of other note/profile action dialogs
