[P1] Restore lowercase cjson component name

The ESP-IDF component registry treats names as case-sensitive and publishes the cJSON library under espressif/cjson. Switching the manifest to espressif/cJSON points the build system at a different package that does not exist publicly and results in the “missing credentials for espressif/cJSON” failure noted in the test output. To keep Tab5 builds reproducible, keep the dependency name lowercase or confirm the uppercase variant actually exists and is accessible.
