fix: show subscription picker for traffic/connect buttons with multiple subs

When user has >1 active subscription and clicks "Докупить трафик" or
"Подключиться" from main menu, now shows inline subscription picker
instead of just an alert. User selects subscription, then proceeds
to the corresponding flow. Removed redundant parse_mode (set globally).
