I refactored several components by removing unused service injections to improve code cleanliness and moved the admin panel link to the user account dropdown for better organization and accessibility for administrators.

• I moved the "Admin Panel" link from the main header navigation (app/components/header/index.ts) to the user's account dropdown (app/components/header/account-dropdown.hbs). I added an action in app/components/header/account-dropdown.ts to open the admin panel in a new tab, visible only to users with admin privileges.
• I removed unused AuthenticatorService injections from app/components/concept-page/content.ts, app/components/course-leaderboard/invite-button-entry.ts, app/components/course-overview-page/notices.ts, app/components/course-page/course-stage-step/community-solution-card/header-label.ts, and app/components/track-page/course-card/stage-list-item.ts.
• I removed unused CoursePageStateService injections from app/components/course-page/course-stage-step/stage-incomplete-modal.ts, app/components/course-page/course-stage-step/your-task-card/index.ts, and app/components/course-page/introduction-step/create-repository-card/index.ts.
• I removed unused MonthlyChallengeBannerService injections from app/components/course-page/sidebar/monthly-challenge-banner.ts and app/components/pay-page/monthly-challenge-banner.ts.
• I removed the unused DarkModeService injection from app/components/copyable-terminal-command.ts.

I refactored several components to inject necessary services, primarily AuthenticatorService, CoursePageStateService, DarkModeService, and MonthlyChallengeBannerService. This makes authentication status, course page state, dark mode preferences, and monthly challenge banner logic readily available, improving modularity and access to shared application state.

• I injected AuthenticatorService into app/components/concept-page/content.ts, app/components/course-leaderboard/invite-button-entry.ts, app/components/course-overview-page/notices.ts, app/components/course-page/course-stage-step/community-solution-card/header-label.ts, and app/components/track-page/course-card/stage-list-item.ts to access user authentication status.
• I injected CoursePageStateService into app/components/course-page/course-stage-step/stage-incomplete-modal.ts, app/components/course-page/course-stage-step/your-task-card/index.ts, and app/components/course-page/introduction-step/create-repository-card/index.ts to manage course page specific state.
• I injected DarkModeService into app/components/copyable-terminal-command.ts to allow the component to adapt its appearance based on dark mode preferences.
• I injected MonthlyChallengeBannerService into app/components/course-page/sidebar/monthly-challenge-banner.ts and app/components/pay-page/monthly-challenge-banner.ts to centralize monthly challenge banner logic.
