## Problem
The new project form has accessibility issues:
- labels are not linked to inputs
- description are not linked to inputs
## How to test
Navigate through the form inputs with voice over and make sure every
input makes sense

## Summary by CodeRabbit
* **Bug Fixes**
* Improved form field identification consistency across project creation
screens (compute size, database password, project name, PostgreSQL
version, region, and organization).
* Enhanced selector/input accessibility by adding explicit element
identifiers to key controls.
* Updated region and repository UI structure to improve reliable
rendering without changing setup behavior.
* Preserved existing password, version, and routing logic while making
dropdowns and fields easier to locate and interact with.

## Problem
We used to have a `_Shadcn_` suffix for all the shadcn form components
because we also had `formik` form components.
This is not needed anymore.
## Solution
- Remove the suffix
- Update all usages
* Break down new project page into smaller components
* Fix types
* Address comments
* Add min length check for project name in project settings
* Fix tests
