Optimalization & few updates

[sramekmichal]

This is quite nice application that you created 👍🏻 We should develop it more.

Next possible feature we should focus on:

• expanded search (now it indexes only repo name)
• dark mode
• color editing (for example header could be customized with even header name)
• when message written by dependabot, it makes it too much wide (it would be nice to shorten it)
• login via github account
• helm chart for kubernetes
