Fix teacher navbar broken routes and add Markdown rendering in Virtual Lab

[Copilot]

Teacher sidebar nav linked to /teacher/students and /teacher/results which had no corresponding routes, causing silent redirects to /login. Lab instructions were rendered as unstyled plain text.

Changes

Routing (App.jsx)

• Added /teacher/students and /teacher/results routes, both rendering TeacherDashboard with an initialTab prop

Navbar (Layout.jsx)

• Replaced exact path matching (===) with per-item exact flag; top-level /teacher uses exact match, sub-routes use startsWith

const isActive = (item) =>
  item.exact ? location.pathname === item.to : location.pathname.startsWith(item.to);

Teacher Dashboard (TeacherDashboard.jsx)

• Tab state now derived from URL via useLocation; tab changes call navigate() to keep URL and UI in sync
• Page title reflects current view ("Students" vs "Student Results")

Virtual Lab Instructions (VirtualLab.jsx)

• Installed react-markdown; experiment description and each instructions step now rendered through <ReactMarkdown> enabling bold, italic, code, and list formatting

Original prompt

[Chronological Review: The conversation began with the user requesting to run a project, followed by a request to fix issues and run the project again. The user then reported a timeout error related to the `users.findOne()` operation while attempting to sign in. The user provided their email and password, indicating their role as either a student or teacher. The user expressed dissatisfaction with the lab interface and requested fixes for the teacher side and navigation bar, suggesting the use of Markdown for improvements.]

[Intent Mapping:

1. "run it please" - User wants to execute the project.
2. "fix it please and run the project" - User requests fixes and execution.
3. "fix tat please and i need des user run so try it please" - User reports a timeout error and requests to fix the sign-in process.
4. "so please i don't see that lab like that please and fix the teacher side and fix the navbar because it has many problems and use markdown maybe help you" - User requests improvements to the lab interface, specifically for the teacher side and navigation bar.]

[Technical Inventory:

• MongoDB: The user encountered a timeout error with the users.findOne() operation, indicating a potential issue with database connectivity or query performance.
• Markdown: Suggested by the user for improving documentation or interface elements.]

[Code Archaeology: No specific files or code changes were discussed in detail, but the user is working on the /home/islem23/taher/docs/PLATFORM_OVERVIEW.md file, which likely contains documentation or specifications related to the project.]

[Progress Assessment:

• Completed Tasks: User has provided feedback on the lab interface and sign-in issues.
• Partially Complete Work: Fixing the timeout error and improving the lab interface are ongoing tasks.]

[Context Validation: All critical information for continuation is captured, including user requests for fixes and improvements.]

[Recent Commands Analysis:

• Last Agent Commands: The user requested to run the project and fix various issues.
• Tool Results Summary: The user encountered a timeout error with the users.findOne() operation, indicating a problem with the database query.
• Pre-Summary State: The agent was actively addressing user requests related to running the project and fixing the sign-in process when the token budget was exceeded.
• Operation Context: The commands executed were directly related to the user's goals of running the project and resolving issues with the lab interface.]
