FR: Materialization Summary section

[jwhartley]

Context: We quite a complex product, and there are a lot of different options for a materialization. This is partly spawned from the target naming issues some customers have had, but customers face issues with soft/hard deletes, storage mappings, standard / delta updates, and sync frequency.

Feature Request: Create a Materialization Config Summary section as the last section when editing a materialization. This section will give a one-pager of how the materialization is set up, and what it's going to do / how it will behave. Optional and doesn't require any user interaction if they don't want, but gives concise & valuable information if they do.

Use cases:

1. I'm relatively new to Estuary, and I want to confirm I've set up a materialization correctly. Do I have the right data sources / collections enabled? Are deletes going to behave right? I don't even know there's a difference between standard and delta updates, am I doing it right? I'd like a quick summary of what I've set up so I can confirm it's correct. Heck I might even send it to my more experienced colleague to confirm.
2. I'm an experienced Estuary user, but I skew conscientious and neurotic, I'd like to double-check that I've set up this new materialization right.
3. I'm an experienced Estuary user, and something's gone wrong with my materialization (data isn't appearing where I expect). I'd like a summary to check the key details of my materialization.
