feat: replace native confirmation popups with antd popconfirms

[eglitise]

This PR is a style change for the confirmation dialogs that appear when deleting a saved capability set or gesture.

• The current implementation uses the native browser alert/Electron full window popup, which blocks all interaction with the application until either of the two prompt options are selected.
• The proposed implementation switches to the antd Popconfirm component, which offers several benefits:
  • More lightweight UX
  • Consistent style with the rest of the app
  • Automatically dismissed upon any action outside the dialog
  • i18n support

Note: antd does not auto-hide tooltips on click, so for saved capability sets, the zIndex prop was used to place the tooltip behind the popconfirm.

Do we only want to replace a single session deletion confirmation popup in this PR or there are more?

[eglitise]

These are the only two instances of window.confirm in the Inspector code.

Both changes are applied to every element within their lists, so this will replace all instances of the deletion confirmation popups.

[mykola-mokhnach]

I mean maybe there are other types of alerts, for example informational ones, and we'd like to replace them as well

[eglitise]

True, we do use notification in various places, but antd also offers message, which may be more useful in some locations. That can come in a separate PR though 🙂
