Normalize screen layouts: extract control groups, unify sidebar widths, and refactor PromptsScreen

- Extract ToolControls group from ToolsScreen (search, list, list-changed indicator)
- Extract PromptControls and PromptListItem groups for PromptsScreen sidebar
- Refactor PromptsScreen to sidebar + detail layout (matching ResourcesScreen pattern)
- Refactor PromptArgumentsForm to accept a single prompt instead of a dropdown
- Normalize all screen sidebar widths to 340px (Tools, Resources, Prompts, Logs, Tasks, History)
- Convert ToolsScreen from Grid-only to sidebar + Grid layout
- Replace LogControls checkboxes with full-width toggle buttons
- Move Clear/Export buttons from LogControls to LogStreamPanel toolbar
- Make PromptArgumentsForm "Get Prompt" button right-aligned and compact
- Update all affected stories and ConnectedView
