Validation issues when creating a new model

[mlqn]

Description of the bug

1. The regex allows invalid formats

Entering a. or (space) as a name is valid on the frontend but invalid on the backend.

regex.mov

2. The error message does not reflect the regex

Entering 1a as a name is considered as invalid but it's not reflected in the error message

1a.mov

3. The required message is missing

Entering an empty name should display a different message indicating that the name is required, similar to the message shown when trying to enter an empty name while creating an app.

Data model validation (withtout required error message)	App validation (with required error message)
required.mov	creating-app.mov

4. The error message is not cleared

When you close and reopen the dialog, the input text is cleared, but the old error message is still visible.

5. The input field is not focused

The input field should be focused when the creation dialog opens

6. Max length missing

A maxLength is missing on the input field, allowing long names that causes a backend error

max-length.mov
