Refactor admin panels to utilize CreateNameDialog for creating new entities

Updated the BumpersPanel, ChannelsPanel, CollectionsPanel, GroupsPanel, ClipGroupPanel, and ShowsPanel components to replace direct input fields with a CreateNameDialog for creating new items. This change enhances user experience by centralizing the creation process and improving UI consistency. Localization strings were also updated to reflect new dialog titles and labels in both English and Russian.
