Fix: Sync Feature

[mit-27]

Issues

1. Unified GET APIs will not return data until the initial sync is complete. Once the sync is finished, data will be available in the database for Unified GET APIs.
2. Unified objects are associated with each other. Currently, synchronization for all unified objects occurs in parallel, which assigns null values to the foreign attributes of these unified objects.

Possible Solutions

1. Once the connection is created, the initial sync should trigger which stores the data from the third-party provider to DB. After that, the periodic sync can happen according to the user's settings.
2. Maintain the sync order for unified objects based on their associations. For instance, the ticket object depends on the collection object, so in this case, we need to sync the collection object first, followed by the ticket object.
