Is this flasher realy on/off at all times once power is supplied to unit?

First of all it is not a flasher relay as does not have a timer installed inside it is a standard relay with normally closed or open contacts and when power supplied to it the contacts will operate depending on which tab you have wired to will make or break the supply to the device being powered I use for switching vac pumps on braking systems for locos on a small railway.

Is this a latching relay? Push a button to start, then push a button to stop?

noo. you don't have to push any button , it start automatically and stop automatically ,, ( by current )

Will it be able to switch a 36v main with a 12v signal input?

It's rated 12 volts so unlikely. Fine for car spot lights or in my case heated windscreen.

From what I know of relays, the diagram on this listing shows incorrect wiring. Can you confirm please?

Hello, the diagram on this listing shows is correct, pin85 and pin86 can connect battery and ground in reverse
