I think you will need a scan-doubler if you want to use that monitor with an Amiga. Vertical 55-75 Hz will not show PAL at all as that requires 50Hz, but will show NTSC at 60Hz.

Horizontal 30-82 KHz is indeed "multisync" but does not go down far enough to 15.60 KHz (PAL) or 15.72 KHz (NTSC). So either of these will need to be scan-doubled. PAL/NTSC interlaced modes are still at 15.60/15.72 KHz. Doubled screenmodes are also (mostly) not above the 30 KHz minimum of that monitor.

It's a VGA compatible display.

Are "Flicker-fixer" and "Scan-doubler" one and the same?

No. A scan-doubler does exactly what it says - it doubles the scan rate - but it does not of itself remove the flicker of an interlaced display.

A flicker-fixer is also known as a de-interlacer. VGA monitors are quite capable of showing interlaced screens (with the accompanying flickering), but they need 30+ KHz.

15 KHz LCD displays are indeed available, they're called televisions.
