Some offices require it and some don't. For the ones that do, normally they just want you to get a copy of the ID card and house book of a Thai person, that person doesn't actually have to go to immigration with you. I'm not sure if there's a form for it or not though.

You could do that, but if you ever need to go back to your bank and they want to look at your passport, they could close your account. Or if they decide to do a new wave of KYC in the future and freeze accounts until the owners come in for verification, you could lose it then as well.

Owning property isn't really relevant. Banks don't care about that, they care about the visa status.

you can use any agency, don't have to keep using the same one. But if you're not clear for this one (which sounds like the case) you could try an agency that will use your immigration office and your own money which will clear you for your own next year.

1) When did you deposit the 850k? Was it deposited before the agent got you an extension? If not, then you cannot get this extension yourself.

2) What province is the extension from? If it's from this far flung province, it's probably known for agent extensions and likely they'll tell you to use an agent again when you go into immigration and they see where your last extension was from. The TM30 isn't really relevant.

Only reports I've seen asked are proof of 20,000 baht and proof that you're still attending whatever class you used to qualify. No departure ticket

The marriage visa doesn't allow you to work. A work permit allows you to work. But a marriage visa does allow a company to apply for a work permit for you if you're eligible and they're able to sponsor a foreign work permit.

Only one thing in all of this is relevant. When people did TM30 or you moving doesn't matter.

When you entered Thailand, you start counting from day 1. Your 90 day report is due in 90 days from then.

Immigration doesn't share systems with other countries, but you normally get a stamp in your passport if you're denied entry that anyone can see

"basic" visa doesn't mean anything. That's not an immigration term.
