Improve NDI Usage Experience

• Make the usage easier for user. Add NDI information like Stream Source from the dashboard.
• Remove the mapping setting

@burak-58 @mekya - what is the benefit of removing the mapping setting? I see value in it for automated use-cases, where the broadcast team follows a playbook (turn on media server, turn on studio equipment, etc. - I worked with teams who operate like for a weekly event.) The zero-touch approach makes their life much easier, compared to having to click around on the UI every time to create the stream - or having to run a script that repeatedly queries NDI sources from ant media and then creates the stream via API). - My suggestion would be keeping that configuration option (given it is already an investment we made, it is documented, production ready, etc.) and just improve the experience for other types of users who find the UI easier. What do you think?
