bmpradeep/CRMCalendar ? reverse-engineered prompt

Build me a small Python app that reads two meeting export files, one from CRM and one from the calendar, and shows a single unified list of meetings in a browser.

I want the page to make it easy for a sales team to see which rows are the same meeting, which ones only exist in one source, and which fields disagree. If a meeting has a mismatch, show both versions side by side and highlight the differences instead of trying to pick a winner. Keep the original data files read only, and restart the app to pick up changes.

Also add a simple route list page, a health check, and a terminal mode that prints the same meeting list. It should support searching and filters like conflicts only, CRM only, calendar only, or both. Please make the matching smart enough to handle messy dates, timezone differences, duplicate calendar copies, and cases where a missing value should stay as unknown instead of being treated as a conflict. If you need current docs for anything, look them up online.
