Not sure what country you are from but PayID must be a specific name for a service in your country that sounds like Promptpay in Thailand, FPS in Hong Kong, Zelle in America and a bunch of similar services in different countries. You must set up Promptpay through your Thai bank directly. Such services are country specific.
If you are saying your landlord has already submitted your info for your arrival into the online TM30 system, then all they have to do is take a screenshot of their submission and you simply print it out and keep it as your proof of filing. This is perfectly acceptable and you don't need to go get a paper version from immigration. Tell your landlord that there is an option on the TM30 portal to check submissions by date, which will search for and display results, and they then screenshot that search result page which shows your details that were submitted into the system. I would say the vast majority of foreigners have screenshots of their online filed TM30s, not some old fashioned paper receipt from immigration. I've attached an example as a comment below, of what the proof will look like, whether filed in person, via the online TM30 website, or via the TM30 app. In your case, if your landlord filed online, they will send you a screenshot that looks like the yellow image in the middle. That's what you print and keep as your proof of filing. Nothing further is needed for you to do.
Travel insurance can typically only be purchased before departing for your trip. You should instead buy Thai medical insurance, similar to someone living here. Or if you are here short term and already have an existing expiring travel insurance policy, they normally can be extended directly with the insurer. You just can't buy a brand new travel insurance policy when already in mid trip.
Still commonly in use. They are not treated differently than bills with the current king. ATMs are still dispensing old bills as usual mixed with new ones. They aren't being taken out of circulation.
further proof that MFA doesn't have the right info: it says people only need

baht a family, on the rare chance they ask you to show it. You were literally arguing with the moderator of this Thai visa group as if he of all people wouldn't know the correct requirement.
there is no such 180 day rule. Every entry is at the discretion of the immigration officer. Please stop quoting non existent rules based on your own personal experience with an immigration officer. They chose to hassle you about your stay history, not because you were exceeding a specific number of days.
the point is that the 45 day stamp is for Visa exempt entries and is not a visa. If you were simply stamped in without purchasing a visa, then you do not have a visa, and you entered via visa exempt status. If you truly had a 90 day visa, by definition, you would be stamped in for 90 days. If you were stamped in for 45 days with such a visa, then the immigration officer did not notice the visa you bought, and assumed you were coming in by visa exempt and stamped you in incorrectly for a visa exempt entry rather than using the 90 day visa you paid for.
