[backport cloud/1.37] [refactor] Manager dialog simplification (#8306)

Backport of #8041 to `cloud/1.37`.

**Original PR:** https://github.com/Comfy-Org/ComfyUI_frontend/pull/8041

## Changes
- Consolidated ManagerDialogContent, ManagerHeader, ManagerNavSidebar,
RegistrySearchBar, and SearchFilterDropdown into single ManagerDialog
component
- Added v-model:rightPanelOpen to BaseModalLayout for external panel
state control
- Removed unused useResponsiveCollapse composable, TabItem and
SearchOption types
- Moved action buttons (Install All/Update All) from header-right-area
to contentFilter area

## Conflict Resolution
- **GlobalDialog.vue**: Kept settings-dialog-workspace styles, removed
manager-dialog styles (now in BaseModalLayout)
- **BaseModalLayout.vue**: Kept HEAD version (from #8256 backport) which
has improved grid-based layout with accessibility features
