"""
Fix Gin radix tree param name conflicts in router.go.
Strategy: unify all param names at the same path position to match Chatwoot conventions.

Known conflicts:
1. conversations/:id vs conversations/:conversation_id → use :conversation_id (matches Chatwoot)
2. accounts/:id (in webhook routes) → already fixed to :account_id
3. notifications/:id → no conflict with sub-resources
4. push_subscriptions/:id → no conflict with sub-resources

For conversations: change all :id under conversations group to :conversation_id
and update corresponding handler code.
