Description

What would you like to be added: In the manual scaling window for deployments, stateful sets (and maybe others, I don't know what else can be scaled manually) add a text box to be able to input the new replicas count by typing digits. On the first single click all the content of the box should be selected so that inputting the new value will remove the old one.

Why is this needed: If I need to increase/decrease deployment count by a couple of items then I can click on "+" and "-" buttons. If I want to scale a deployment from some value to a zero I can use the slider input. But if I want to scale a deployment from 0 to, for example, 6 now I need to precisely move the slider or press the "+" button several times and both ways are annoying. An ability to specify the required replicas count from a keyboard could solve that.

Environment you are Lens application on:

  • Kubernetes distribution: AKS
  • Desktop OS: Windows 10 PRO

Research direction
Look at the manual scaling dialog component in the Lens repository, likely under `src/renderer/components/` such as `+scale dialog` or similar. Examine how the current +/ buttons and slider are implemented, and add an `<input type="number">` with appropriate styling and behavior (select all on click). The existing code handles replicas count state; integrate the new text input to update that state. Check if there are any existing PRs or discussions referencing this feature for additional context.
