Four tweaks from a first run of maintenance pages in production.

• Times name their zone. The Starts and Ends labels on the incident form now say which zone they're entered in, e.g. "Starts (UTC)", the name of the app's Time.zone. A hint under Starts gives the current time in that zone when the page loads: "It’s 14:29 UTC now." I went with labels rather than a timezone picker.
• History is the default view. /incidents is now the history, with the type, service and search filters, and New incident and New maintenance buttons in the upper right. Active and Upcoming sections sit above the month-by-month list of resolved incidents and completed maintenances, so a live incident never sinks below future maintenances. Both sections follow the filters, and Upcoming is sorted soonest first. /incidents/history 301-redirects to /incidents, passing on only kind, service, q and page.
• New maintenance starts empty. Choosing services used to autofill the title and first update with the top suggestion, which was usually the last mail-in maintenance. The suggestions Stimulus controller gains an autofillUnless value (a CSS selector), and the new form passes #kind_maintenance:checked. Autofill pauses for maintenances, and switching from Incident to Maintenance clears any text autofill put there. Suggestions still open on focus, and incidents autofill as before. A blank first update still saves as "Maintenance scheduled.", which keeps internal services off the public page.
• "Incidents" reads "Events". The header link is now "Events" and back links read "← All events". I didn't add separate Incidents and Maintenances links, since the filters on the page cover that.

CHANGELOG is updated under Unreleased → Changed.

Testing

The pausing and clearing of autofill is untested: the repo has no JS or system test harness, and I haven't tried it in a browser. It needs a manual check, please.

New integration tests cover the page sections and their order, the buttons, the filters, the redirect (including that it drops unknown keys such as script_name), the zone labels and hint, and the autofill attribute on the maintenance form.

bin/rails test passes except three Playwright probe tests, which fail locally because Chromium isn't installed on this machine and fail the same way on main. Rubocop and Brakeman are clean.

🟡 Changes recommended

The status enum overrides the timestamp-based resolved scope, causing completed maintenances to disappear from both Active/Upcoming and incident history.
