feat(monitors): Monitors absorbs the Status page; Status is removed (#5270)

Status repeated the Monitors page's counts, check strip and uptime. Monitors
now has one header row and every column Status had: the last 30 checks,
latest response with its trend, uptime over 24h / 7d / 30d (the range picker
goes) and TLS days on every row. /status and /status/rows and the nav link
are removed outright; the dashboard Overview (/status/widget) stays and its
Details link goes to Monitors.
