feat(blogs): add Parham's enterprise architecture and executor/worker posts

[elliotgunn]

Summary

Two new blog posts by Parham, from the June 4th webinar:

• [June 10] From 37 million monthly executions: how enterprise teams structure Kestra at scale — covers the three-layer model for enterprise deployments: infrastructure scaling, team isolation via namespaces and tenants, and execution placement with worker groups.
• [June 15] The executor/worker split: the design decision behind Kestra's distributed architecture — covers the component model, Kubernetes replica counts, backend selection, and worker group patterns for multi-region, hybrid, and GPU workloads.

The two posts cross-link to each other and will be crossposted to Medium.

Test plan

• Both posts render correctly in the blog
• Internal doc links resolve
• Cross-links between the two posts work
• Diagram images load
• Parham's review
• Nico's designs for the banner images https://github.com/kestra-io/design/issues/77 — the current main.png files are generated placeholders
