Convert Arena VCL into Rust code in TS to not require extra CDN VCL hop and increase reponse times

[jevansnyc]

Description

We need to solve for Arena sites being able to pull directly from nextjs origin in front of WP without the need to cycle every request through a separate VCL layer. There are specifics we need to address such as:

1. Datadome server-side integration (Compute + Rust is more efficient)
2. Legacy redirects
3. Multi-backend strategies
4. Domain normalizations
5. Hashmap based domain lookups
6. Staging strategy

Done when

• Requests to autoblog are working as normal
• No errors for site content and widgets
• Datadome validation is proxied and working as normal for unwanted and wanted bots
• Site functionality is 100% of today's

Affected area

HTML processing / JS injection
