Updated logging statements in rewrap.go

The logging statements in the "getEntityInfo" and "Rewrap" functions of rewrap.go have been updated for increased clarity and more detailed error tracking. This includes changing the level of some logs from 'warn' to 'error' when an issue arises while obtaining a token, and adding more context information to debug logs.
