Missing categories on deployment comparison page

This page: https://www.elastic.co/docs/deploy-manage/deploy/deployment-comparison

has lots on it, but is missing certain things that would be nice to surface, e.g.

* autooops: self/eck/ece access through CCM, others on by default
* privatelink: only available for ECH
* etc.

AI suggested the following additional categories:

- Cost/Pricing: Since the parent page mentions cost considerations, you might want a comparison row about pricing models (SR: I think we should skip this one)
- Support and SLA: Different deployment types have different support models (SR: maybe same?)
- Upgrade process: How upgrades are handled differs significantly across deployment types
- API access: Availability of REST APIs, management APIs, etc.
- Networking/Connectivity: VPC peering, private link, IP filtering, etc.
- Backup/Recovery: Currently only "Snapshot management" - could expand on disaster recovery procedures
- Performance tuning: Control over JVM settings, index settings, etc.

# Action

try to bulk up this page with some differences. a good starting point would be going through all of the overview pages in the deploy and manage section to find what we highlighted lower in the docs.
