[Story]: User-card indicators — onboarding-completed badge + reorder-request indicator

[adoLime]

User Story

As a PM, I want user cards in the team list to clearly distinguish members who completed onboarding from those still in progress, and to show a pending reorder-request indicator alongside the existing feedback and skip-request indicators, so that I can spot at a glance who needs my attention.

Context & Motivation

• Type: Functional (Onboarding / PM)
• Parent epic: 06 EPIC - Onboarding Journey & Digital Adoption #55 (06 EPIC – Onboarding Journey & Digital Adoption)
• Teams: team:frontend (card indicators)
• Related: [Story]: Feedback on generated onboarding path #184 (feedback signal — already implemented on TeamMemberCard), [Feature]: Rework Onboarding Step #214 (skip-request signal — already implemented on TeamMemberCard), [Story]: Request to reorder onboarding steps #226 (reorder-request signal — Sprint 5).
• Sister story: "PM dashboard — project list & project drilldown" (covers the project list + drilldown structure; this story covers the per-card badges).
• Design system: per AGENTS.md §7, never rely on colour alone — badges must use icon + text label.

Dependencies

• Depends on: [Story]: Request to reorder onboarding steps #226 (reorder-request signal source — Sprint 5) for the reorder-request indicator.
• No new dependency for the completed-vs-in-progress badge (reuses existing progressPercentage / currentStep fields on TeamOverviewUser).
• Reuses: existing feedback ([Story]: Feedback on generated onboarding path #184) and skip-request ([Feature]: Rework Onboarding Step #214) indicators on TeamMemberCard — kept as-is.

Acceptance Criteria

• TeamMemberCard shows a clear "Onboarding completed" vs "In progress" badge (icon + text label, not colour alone — per design system §7 accessibility).
• TeamMemberCard shows a pending reorder-request indicator (icon + text label) when the user has a ReorderRequest with status = pending (reuses [Story]: Request to reorder onboarding steps #226 signal), parallel to the existing skip-request indicator.
• Existing feedback indicator (yellow MessageSquareText badge, [Story]: Feedback on generated onboarding path #184) is kept.
• Existing skip-request indicator (red SkipForward badge, [Feature]: Rework Onboarding Step #214) is kept.
• All four indicators are mutually distinct and readable in light/dark themes (per design system §7).
• Empty / loading / error states; i18n (en/de).

Sub-Tasks (by team)

• Frontend — "completed" badge on TeamMemberCard; reorder-request indicator on TeamMemberCard (parallel to skip-request, reuses [Story]: Request to reorder onboarding steps #226 signal).
• QA — tests for rendering of all four indicators (feedback / skip / reorder / completed) in pending and non-pending states, light/dark theme.
