fix: correct caller frames in GORM logger and DB arg in main

- add *Skip variants (logSkip, makeLogFieldsSkip, getLoggerCallerInfoSkip)
    so wrapper functions report the true call site, not logger internals
  - switch GormLogger.Trace to use ErrorSkip/WarnSkip/InfoSkip with extraSkip=1
    so SQL log lines point to GORM caller rather than the logger facade
  - pass postgresDBClient instead of tx to GetFullMeasurementSet in main
