fix: use oci.resourceName for OCIMYSQLDATABASE entity synthesis

The synthesis rule incorrectly referenced oci.resourceDisplayName which
does not exist in the actual metric payload from oci-metric-streams.
This caused entity synthesis to fail silently, resulting in entities
with type NA in the GUID that never appear in the catalog.

Changes:
- definition.stg.yml: name field changed to oci.resourceName (matching
  other OCI entity definitions like autonomousdatabase and postgresql)
- definition.stg.yml: goldenTags updated to only reference attributes
  that actually exist in metric data (oci.compartmentId, oci.region,
  oci.accountName)
- tests/Metric.stg.json: updated to match real metric payload structure
  from oci-metric-streams collector
