Bug: Atomic Editor causes HTTP 508 (Loop Detected) / Resource Limit Is Reached on Low-End Apache Servers

### Description

When enabling the Atomic Element / Atomic Editor feature in Elementor settings, the Elementor Editor panel fails to load completely (stuck on the loading screen). Upon inspecting the browser console and network tab, the server throws multiple HTTP 508 (Loop Detected) errors alongside a "**Resource Limit Is Reached**" response from the hosting environment.

This issue specifically occurs on lower-end/shared hosting environments powered by Apache Web Server, as the high volume of concurrent/granular REST API requests sent by the Atomic Editor completely exhausts the server's CPU, I/O, and Entry Processes (simultaneous PHP scripts limit).

Interestingly, the exact same project works flawlessly on a Staging Server running Nginx, despite having lower overall memory allocation, because Nginx's event-driven architecture handles these simultaneous atomic requests much more efficiently.

### Steps to reproduce

1. Use an Apache-based shared hosting environment with standard/low resource limits (e.g., low Entry Processes and CPU limits).
2. Go to Elementor > Settings > Features (or Advanced) and Enable the Atomic Editor / Atomic Element feature.
3. Attempt to open any page with the Elementor Editor.
4. The widget panel on the left will get stuck in an infinite loading loop.

**Console Log Error**

**Network Error**

5. Deactivating the Atomic Editor instantly resolves the loading issue (but breaks the layout previously built with it).

### Expected behavior

The Atomic Editor should optimize request batching or throttling when deployed on Apache servers to prevent triggering server-side protections like CloudLinux LVE limits (HTTP 508 / Resource Limit Reached).

## Isolating the Problem
- This bug happens ONLY when the Atomic Editor feature is active
- Tested with ALL plugins deactivated except Elementor
- Tested with default Hello Elementor Theme.
- Increasing WP_MEMORY_LIMIT via wp-config.php does not resolve it because the Apache server hits the Physical CPU/Entry Processes limit first due to the massive influx of concurrent REST API requests (/wp-json/elementor/v1/...).
