refactor: Update indexing status display in connector components

- Replaced the previous "Syncing..." text with a more concise "Syncing" in various components to enhance clarity.
- Adjusted the UI to maintain consistent styling and improve user experience during indexing operations.
- Simplified conditional rendering for indexing status across ConnectorCard, ActiveConnectorsTab, and ConnectorAccountsListView components.
