The official yellow Vaccine passport for vaccinations in Thailand are normally issued by the hospital where you got your Covid vaccination. They won't issue you one if you only have foreign vaccinations, but they will add your previous foreign shots to your vaccine passport if you provide it to them at the time they issue the vaccination passport for your Thai booster. You didn't get a vaccination record wherever you got your vaccinations?
there is no such thing as a 15 day extension. You either are granted 30 days or if rejected, granted 7 days extra to depart. There's no in between. Don't argue with

no, it can be done at any clinic or doctor in Thailand. Very basic form they fill out after just taking a look at you, and costs only a few hundred baht to get one.
If you have a valid driver's license from your country and a valid international drivers permit from your country, then you don't need to pass any exams to convert your foreign license to a Thai license. Just show your country's license and IDP at the Department of Land Transport together with medical certificate and a residence certificate or work permit, and you can get your Thai license instantly.
it's a bit shocking to read that you've been resident of a country or region for a decade yet don't know what paperwork or documents are given in that country to indicate residency. You keep blaming the Thai consulate instead of you not understanding the rules for residency in wherever you are living. It's not their job to tell you how Laos or Cambodia will consider you legally a resident so that you qualify to apply for a visa from the Thai consulate there. If you've just been using tourist visas to stay extended periods in various countries, then you are by definition a tourist and not a resident of those countries. It's pretty much common sense.
No one is playing games and no one is looking for a bribe, as you claim. A consulate's job is not to advise you how to become a resident of whatever country you are in at the moment. Why blame them when you don't seem to know the residency rules of wherever you are? As others pointed out, the requirement is not unusual in any way. You just decided to be indignant and expect them to handhold you.
