Debug logs should not use magic number level 1 `V(1)`

logger.V(1).Info("NonAdminBackup Reconcile start")

Perhaps per https://pkg.go.dev/github.com/go-logr/zapr#hdr-Implementation_Details

Levels in logr correspond to custom debug levels in Zap. Any given level in logr is represents by its inverse in zap (zapLevel = -1*logrLevel). For example V(2) is equivalent to log level -2 in Zap, while V(1) is equivalent to Zap's DebugLevel.

Basically use zapcore.DebugLevel with an adapter function to inverse the number.. so zap.DebugLevel will return -1 and we *(-1) it when used with logr.Logger.
