Seperate name and display name and filter case-insensitive

[Voltstro]

Currently, project filtering is case-sensitive. If a user visits https://projects.voltstro.dev/UnityWebBrowser all is good, the project page will load, but if a user visits https://projects.voltstro.dev/unitywebbrowser, VoltProjects will come back with a 404 error.

This is happening because the unique name column is what is used for getting what project a page belongs to. The name column is also currently used for display reasons.

Normally, to compare strings Case-Insensitive, you use .Equals(comparing, StringComparison.InvariantCultureIgnoreCase), but with EF, that does not work, as we need to use Collations.

• Create new "display_name" column. UI will use this for displaying (as well as short_name on small screens).
• Add a non-deterministic collation and apply it the name column, and project_version.latest See https://www.npgsql.org/efcore/misc/collations-and-case-sensitivity.html?tabs=data-annotations
