Implement the project install step

[sodic]

Important

I messed up the base branch when merging this. The entire discussion is here, but the commit that ended up in main is in this PR: #1690.

Fixes #1597.

Tasks:

• Add an extra install step during wasp start
• Decide what to do with the dependencies field in .wasp files - I decided to remove the field and only keep a single source of truth, the `package.json file.
• Update the docs.
• Fix wasp not installing npm deps that are in package.json but are not installed. -> fixed in Restructuring: fix npm deps installation + fix unit tests #1652 .
• TODO: https://github.com/wasp-lang/wasp/pull/1602/files#diff-aa79f536fd3bb9203f9d976c63594a52a9f3533759e2b754e2a6baec6403a7dbR95-R96 -> this is the one that the only unresolved comment is about.

How to run and test stuff:

• Go to waspc/examples/todo-typescript and work inside that project.
• Running ./cleanstart will clean everything, fix known issues (e.g., duplicate react) and start the app with all the necessary migrations applied.
• The rest of the commands (e.g,. cabal run wasp-cli start, cabal run wasp-cli clean) will do what you expect.
• After each change, either let the application pick it up, rerun cabal run wasp-cli start, or run ./cleanstart (depending on what you're changing).
• You can run ./fix to fix the double react installation issue (but often won't need to, as ./cleanstart takes care of it).
• Please don't commit the migrations or package-lock.json.

PR 1603 (filip-wasp-reset) branches out of PR 1604 (filip-restructuring-prisma), which branches out of PR 1602 (filip-project-install-step).
The PR numbers are unfortunately out of order.
Make sure you keep the branches up to date with their bases as you change stuff.

Did another round!

Done!

TODO: Update the docs.

I fixed all the comments except for that one you said @sodic not to touch.
I also ran the new code, all seems fine.

[Martinsos]

Ok I actually revived you change to how output in terminal is prefixed, I saw after running it more that it just doesn't look good.

I also did the docs. I hunted down mentions of dependencies and either removed them if redundant or updated them to talk about package.json / npm install .

[Martinsos]

I tried running npm install -S <some_dep> and Wasp picked it up and reacted to it: that worked well! Interesting thing though: this dep was never added to .wasp/out/installedFullStackNpmDependencies.json . Not sure if this is a problem or not at this point -> probably is?

I also tried adding a dep directly into package.json to see if Wasp will pick that up and install it on its own, but that didn't happen. I tried starting wasp start again, and that also didn't pick it up. But might that be ok at this point, due to the shape in which restructuring is and the fact that we are using ./cleanstart thing? Or should this be working?

Everything you mentioned here should be working.
