You should get itemized statements from your patent attorney. You can ask for a copy of the correspondence from foreign associates or offices acknowledging renewal payments. I am a retired patent agent who did a significant amount of foreign filing and I would have been happy to give clients copies of all correspondence and wire transfers, if asked.
I do not believe there is any common international system for tracking what you are asking about. Office actions do have dates and are usually coded in the data of patent offices by type of action but the coding is jurisdiction depend and events do not carry serial numbers.
Individual cases and applications typically are given attorney docket numbers that end up on most all of the back-and-forth correspondence. They are made up by attorneys and agents for their own record keeping and have no official standing. And are optional.
The core official identifiers are application numbers. With a country prefix they will be unique world-wide. Each continuation or divisional will have a unique application number.
