fix: attach auth header on RCA tool MCPInstrumentation events

fetchRCA, getBuildId and listTestIds called trackMCP with config in the
3rd (error) argument slot, leaving the config param undefined. Without
config, no Authorization header is attached and the /sdk/v1/event
endpoint silently drops the event (raise_error:false + .catch), so these
tools logged zero usage despite being invoked. Pass undefined as the
error arg and config as the 4th, matching the other tools.

Fixes AIMCP-187.
