Sync command menu with main context store (#19650)

## PR description

- The command menu in the side panel now reads directly from
`MAIN_CONTEXT_STORE_INSTANCE_ID` instead of snapshotting the main
context store into a separate side-panel instance when opening. This
keeps the command menu always in sync with the current page state
(selection, filters, view, etc.).
- Removed the broadening/reset-to-selection feature (Backspace to clear
context, "Reset to" button) since the command menu no longer maintains
its own copy of the context.
