feat: CMD-187 autocreate search page

[wesleyboar]

Overview

Support a Google Search page with less effort.

What Effort?

Every Time:

1. Create search engine.
2. Configure search engine to match others.
3. Set owners of search engine.
4. Copy search code → ID.
5. Set relevant SEARCH settings.

Previously:

6. Restart the server.
7. Create /search page.
8. Create snippet on page.
9. Paste search code in snippet.
10. Duplicate-or-Neglect search styles from TACC

Now, Instead:

6. Restart the server.

Important

Incomplete because there is a suggestion (which I agree with) to use a custom migration.
Originally built off code from release/v4.36.X when it had been main branch.

Caution

Do not merge.

To Do:

• Rebuild off of main branch.
• Use new solution.

Warning

Successful run requires two deploys. Help wanted.
