what did the territorial waters of world countries looked like during WW1 and WW2 for example?, I know that exclusive economic zones are a very recent concept that were only invented in that 1982 UN treaty, but about territorial waters - did most countries have a consistent concept of this, and if so, how did their territorial waters looked like back then when compared to now?

No, there wasn't a consistent interpretation of territorial waters prior to UNCLOS II (when it was set to 12 nautical miles, in most cases). Most countries claimed 3 nautical miles but some claimed more. Have a look at the 'Background' section of the Wikipedia article (https://en.wikipedia.org/wiki/Territorial_waters#Background) and the Britannica summary (https://www.britannica.com/topic/territorial-waters).

Here's how I eyeball it. I've used two colors because the Laotian border seems to be surveyed differently nowadays, so there's a bit of territory there that's part of Vietnam according to the modern maps but isn't part of either North or South Vietnam according to the contemporary map.
