Add incident links to scheduled maintenance entries

[Misrilal-Sah]

Issue link id: #4573

Description:
Planned maintenance entries now link to their incident detail page directly from the scheduled section.
This brings behavior in line with historical incidents and avoids forcing users to guess incident IDs for future maintenance events.

The incident route is defined as incident/{incident} (StatusPageRoutes), so passing ['id' => $schedule->id] will not bind the required {incident} parameter (it may generate a query string or throw a missing-parameter error depending on framework behavior). Use a positional parameter (route('incident', $schedule->id)), the correct key (['incident' => $schedule->id]), or $schedule->permalink (IncidentPresenter already provides this).
