dashboard workspace standard seeds (#16962)

# Introduction

In this pull request we're introducing new standard page layout, tabs
and widget ( 1 page layout, 1 tab and 8 widgets ) and also a new
opportunity field

Also now prefilling new records, 6 opportunities and a dashboard.

## Standard declaration
### New workspace creation
Relies on existing standard declaration builder

### Backfill command
We've been hacking through the standard builder in order to extract only
the standard page layout entities, updated their entity dependencies to
match the workspace ids so the validation passes


## Remark
- Refactored the `PageLayoutWidget` configuration type to be dynamically
typed through a generic discriminated union
