Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the system's operational visibility and resource management by introducing a new administrative dashboard and implementing a concurrent rendering control mechanism. The changes provide administrators with detailed real-time metrics on rendering performance and WebP serving, while also ensuring system stability under high load by limiting simultaneous render processes. This allows for better monitoring and optimization of the application's performance, particularly in high-volume environments. Highlights

Code Review
This pull request introduces a new admin dashboard with real-time metrics for rendering and WebP serving, including total users, devices, active/queued renders, and WebP traffic. It also implements a configurable semaphore (MAX_CONCURRENT_RENDERS) to limit concurrent rendering operations, with logic to prioritize renders for uncached images. Review comments suggest adding documentation for the default MAX_CONCURRENT_RENDERS value and validation for negative inputs, improving error logging for WebP metrics, and adding unit tests for the getLoadAverage utility function.

It's good to provide a default value for MaxConcurrentRenders, but consider adding a comment explaining why 5 was chosen as the default. Is it based on testing or hardware constraints? This will help future maintainers understand the rationale behind the default value.
Also, consider adding a validation to ensure that the value is not negative, and log a warning if it is.

It seems like webpMetrics.RecordWebPServed(0) and webpMetrics.RecordUniqueDevice(device.ID) are called when there is an error. It might be useful to log the error message along with these metrics to provide more context for debugging.

Consider adding a unit test for getLoadAverage() to ensure it returns a valid value, or handles errors gracefully. This is important because the function reads from a file, which could fail.

Might keep this as a high device / volume branch but just wanted to see what gemini was going to complain about.
admin dash,
10 sec stats in log output
default 5 render slots avaailable, return cached if no slots avail.
