DMX-3840 Manifest v4.1 developer docs

[jimj-procoretech]

Initial commit for public facing manifest v4.1 dev docs.

[delta1186]

I am probably not supposed to be able to post here, but since I can here it goes. Here are my observations based on what is currently accessible to developers. If you are developing a side panel app on the current documented manifest or 4.1 the following views currently do not work as per they are currently documented. I think there are others that also do not work, but these are the ones I am focused on currently.

"budgeting.list",
"budgeting.detail",

However, the following view does work, but it is not documented in the PR or the current documents. Just found it on my own.

"budgeting.change_history.list"

Additionally, I would like to see the ability to add the side panel app to the following view. The name could be either one of these.

"forecasting.list"
"budgeting.forecasting.list"

I've been trying to get this fixed through support for over 30 days now. Very frustrating.

@delta1186, thanks for your post and the details. We are aware of your support case. We have had some higher-priority items we had to put before we could get to that, but it is the next thing we are tackling to determine the inconsistencies and what has changed on the tools.

We can look at what is possible for those other areas you requested.
