Wake the app with a headless browser, not curl - #10

A curl request counted as success while the app slept: Streamlit answers it with 200 and its sleep page, and only a browser session counts as a visit. The job now opens the app in Chromium, presses the wake button if the sleep page shows, and fails unless the app itself loads.

The keep-awake job has reported success on every run while the app slept. A sleeping Streamlit Community Cloud app answers a plain request with 200 and its "gone to sleep" page, so the curl check passed, and a request without a browser does not count as a visit.
The job now opens the app in headless Chromium, presses Yes, get this app back up! if the sleep page shows, and passes only once the app's root element (
stApp) has rendered inside thestreamlitAppiframe. It fails if the app does not load within five minutes.The comment on the schedule now says about 12 hours instead of a few days, which is how long an app goes without a visitor before it sleeps.
Tested: a manual run on this branch passed and logged "the app loaded": https://github.com/vidit-16/DocEngine/actions/runs/36358251996. The app was awake at the time, so the wake-button path has not run in CI yet. The button's label and role match the sleep page as it looked today.
