1. /complaints/templates/new/ — TemplateDoesNotExist: template_form.html was
missing. Created a functional template form (name, category, title pattern,
description).
2. /complaints/oncall/schedules/new/ — NoReverseMatch: redirect('dashboard')
should be redirect('/') since the URL name 'dashboard' doesn't exist.
3. /complaints/settings/escalation-rules/new/ — RelatedObjectDoesNotExist:
EscalationRuleForm accessed self.instance.hospital on an unsaved instance.
Changed to self.instance.hospital_id (safe FK ID check).
