perf: code-split xterm bundle and gate terminal features for cloud

- Gate logs-terminal keybinding (Ctrl+`) registration for cloud builds
- Filter out ToggleBottomPanel command for cloud builds
- Gate terminal tab registration in bottomPanelStore for cloud
- Convert terminal tab components to async imports (defineAsyncComponent)
- Dynamic import of useTerminalTabs module ensures xterm bundle is tree-shaken

The ~400KB xterm bundle (vendor-xterm-*.js) is now only loaded on
non-cloud distributions when terminal tabs are registered.

Fixes COM-14129
