In this context, the adverb "ever" means at all times or always. The speaker has used "ever" to express that she is the best boss of all time, and that there will be no boss that can be better than her in the past, present, or future. An expression with a similar meaning is "of all time." Ex: This is the best pizza ever. Ex: This is the best pizza of all time.
