Databases with a large number of partitions (100+) causes the console to freeze

### Version Information

Server Version: latest oss

### Environment

OSS/Cloud/EE

### What is the current behaviour?

Database schemas with lot of partitions causes the console UI to become unresponsive and throw alerts.

### What is the expected behaviour?

The `Manage Database` section of the console should work as expected and list the untracked tables.

### How to reproduce the issue?

1. Track a database with 100+ partitions.
2. Navigate to the `Manage Database` section (click on the database name on the nav tree).
3. The UI becomes unresponsive while trying to load the list of untracked tables.

### Any possible solutions/workarounds you're aware of?

1. Hide the partitions while listing untracked tables in `Manage Database` section.
2. Add pagination to the list of tables.
