fix: sync squads to Remnawave panel on tariff purchase/switch

When sync_squads parameter was introduced (4aaf0ddd) to prevent FK
violations from stale squad UUIDs, all update_remnawave_user calls
defaulted to sync_squads=False. This broke squad synchronization for
purchase/tariff-change flows where squads are freshly assigned and
must be sent to the panel.

Adds sync_squads=True to all purchase, tariff switch, and country
selection call sites across cabinet, bot handlers, miniapp, and
auto-purchase service.
