Bring back ET dashboard per ET request (#7497)

Although mobile benchmark numbers are not used. ET plans to reuse the
dashboard for their server-side benchmark like [CUDA
backend](https://torchci-git-add-et-bm-dashboard-back-fbopensource.vercel.app/benchmark/llms?startTime=Thu%2C%2013%20Nov%202025%2000%3A48%3A48%20GMT&stopTime=Thu%2C%2020%20Nov%202025%2000%3A48%3A48%20GMT&granularity=day&lBranch=export-D87400561&lCommit=7dd02957cbd251726ce8011deda56f189cd4dcd5&rBranch=export-D87400561&rCommit=7dd02957cbd251726ce8011deda56f189cd4dcd5&repoName=pytorch%2Fexecutorch&benchmarkName=&modelName=All%20Models&backendName=All%20Backends&modeName=All%20Modes&dtypeName=All%20DType&deviceName=CUDA%20BACKEND%20(cuda)&archName=All%20Platforms)

Let's know if the dashboard needs to be cleaned up or not
