refactor(web): replace popover with dialog for system status details

Replace the dropdown popover with a proper Dialog for runtime status
details. Add a small info button on the System Status card that opens
the dialog. Session details now show in a spacious 2-column grid layout
with full image name, backend, CPU/memory, network, mount path, and
created/last-used timestamps.
