Add many monitors at once from a list of URLs

You can now paste a list of URLs, one per line, and create an uptime monitor for each. It copes with lists copied from spreadsheets or notes: https:// is assumed, bullets and trailing commas are ignored, and "Name, URL" lines work in either order.

Nothing is dropped silently. Lines that can't be read appear in the preview with the reason, and duplicates are flagged before anything is created. Look for "Bulk add URLs" on the monitors list.
