refactor(deployment): move copyLogs to client-side and hide refund when ineligible

Move copyLogs from PHP Livewire method to Alpine.js to avoid
unnecessary server round-trips. Extract collectVisibleLogs()
helper shared by both copy and download actions.

Hide refund section entirely when not eligible instead of
rendering a permanently disabled button.
