Trial cleanup:
- create_paid_subscription: auto-deactivates all trials when creating paid sub
- extend_subscription: auto-deactivates trials when extending converts to paid
- Works from ALL paths: bot, cabinet, miniapp, webhooks, auto-purchase
Bot handlers:
- Shared resolve_subscription_from_context in common.py with FSM state fallback
- Fixes nested callbacks losing subscription context in multi-tariff
- All 5 handlers (traffic, devices, autopay, links, countries) use shared resolver
- my_subscriptions stores active_subscription_id in FSM state on delegation
