Search Bar in Networks Tab (NetBird Client)

Is your feature request related to a problem? Please describe.
When managing many networks in the NetBird Client, it is frustrating to manually scroll through the Networks tab to find a specific network. This becomes inefficient as the number of networks grows.

Describe the solution you’d like
Add a search bar to the Networks tab that allows users to search and filter networks by IP range, domain/hostname, or network ID (including partial matches).

Describe alternatives you’ve considered
Using naming conventions or manually organizing networks, but this does not scale well and is error-prone.

Additional context
This feature would significantly improve usability and speed up network management in larger environments.
