test(cmd): update tests for layout refactor

Updated unit tests in src/command/cmd.rs to use the new GridLayout-based
CmdContext and layout accessors. Tests now construct CmdContext with a
layout argument and verify behavior of navigation and selection commands
under the refactored layout logic. No functional changes to command logic;
only test updates.
