Wire up isolateConfig to SDK command tests

Add isolateConfig()/restoreConfig() to command test files to ensure
tests are isolated from developer's environment variables (SFCC_*, MRT_*).

Files updated:
- test/cli/base-command.test.ts
- test/cli/instance-command.test.ts
- test/cli/mrt-command.test.ts
- test/cli/oauth-command.test.ts
- test/cli/ods-command.test.ts
