One gotcha is that the land also slopes slightly along the side of the

this end below the outermost row of patio blocks - will a row of
interlocking bricks likely keep the gravel behind them in check, or
should I be looking at doing something a bit more substantial (e.g.
mortared together, and/or foundation, or using blocks that can be staked
into the ground)?

Kerbstones are what I used. Nothing has moved and it was a few years back..
You will of course need some sort of edging or the blocks themselves
will move.
Can you build the ground up so it supports the edge of the paved area?

Also be sure to use sharp sand. Fine sand is displaced in wet weather
and comes up the cracks, allowing the blocks to sink.
