Incident status Filament form label uses wrong translation key

## Priority: P4 (Low - Nice to Have)

## Problem

In `src/Filament/Resources/Incidents/IncidentResource.php:55`, the `ToggleButtons::make('status')` uses `->label(__('cachet::incident.form.name_label'))` — the same translation key as the name field on line 50.

## Suggested Fix

Change the translation key to `cachet::incident.form.status_label`.
