Complex & Multi step actions guide

[zachdaniel]

This guide should talk about:

• changes
• preparations
• how to think about using hooks in both cases
• real-world examples where you might use hooks
• considerations between things like "before action", "before transaction" etc.
• some examples of manage_relationship
• reactor as an alternative way of doing complex workflows (I or someone else can write this part)

It does not have to explain these things in complete depth, we can link to other relevant guides.

I can commit some time to this in the next few weeks. Expect questions on the forum or discord as I work through it since I'm not an expert. :)

@chazwatkins I don't have the practical knowledge to get anywhere on this as a whole myself. But I'd be happy to lend a hand if you find any chunks that can be reasonably delegated.
