Subject: fix(ocpp2.0): align VARIABLE_REGISTRY spec conformance and log severity
X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=3c1c342fd9a082cebe832393eceed749f4dd7555;p=e-mobility-charging-stations-simulator.git

fix(ocpp2.0): align VARIABLE_REGISTRY spec conformance and log severity

Distinguish required vs optional variables per OCPP 2.0.1 spec
(dm_components_vars.csv). Missing required variables log as error,
missing optional ones as warning. Tag 58 spec-required entries with
required: true and 6 non-spec entries with vendorSpecific: true.
