**Use `clsx` for conditional class names**
String template interpolation is used to combine static and dynamic class names here, which violates the project convention of using `clsx` for conditional class composition.

**Relative imports instead of absolute paths**
All four imports here use relative paths (`../helpers/roles`, `../_generated/server`, `../auth`). The project convention requires absolute paths (e.g., starting with `~/` or a package alias) instead of relative paths in TypeScript files.
The same pattern appears in the test file at `packages/backend/tests/web_api/web.user.test.ts` lines 3–8, where all imports use `../../convex/...` and `../helpers/...` relative paths.

**Full table scan on every search request**
`ctx.db.query("users").collect()` loads every user record unconditionally, then for each one issues a separate `authComponent.getAnyUserById` call. With N users that's N sequential auth-profile lookups followed by in-memory filtering.
Even though the result is sliced to 50, all N records and all N auth lookups happen first. As the user base grows this will become very slow and could exceed Convex query execution limits.
Consider paginating the scan or building an index that allows filtering before enrichment, so only the matching users need their auth profiles fetched.

**Self-demotion guard only blocks non-admin roles, not all role changes**
The condition `user.isCurrentUser && role !== "admin"` disables the Student and Teacher buttons for the current user but leaves the Admin button **enabled** on their own row. Because `user.role === role` already disables it when they are already admin, in practice all three buttons end up disabled — but the intent is fragile and confusing.
If the current admin's role were ever non-admin when this page is rendered (edge case in a race), the Admin button on their own row would not be disabled, potentially allowing an unexpected self-role change.
A cleaner and safer guard is:
```suggestion
const isDisabled =
isPending ||
user.role === role ||
user.isCurrentUser;
```
This disables all role-change buttons for the current user's own row, which matches what the backend enforces (`Admins cannot remove their own admin access`) and makes the protection explicit and unconditional.

I think the search term should be part of the sql query so we don't have to return the whole user table. but i don't think this app will ever have more than 5 users to it's fine

TL;DR
Added admin user management functionality with role-based access control and a dedicated admin interface for managing user roles.
What changed?
/adminpage with authentication and role-based access control that only allows admin usersAdminUserManagementcomponent with user search functionality and role assignment interfaceTeacherDashboardto show admin-specific features and "Manage Users" button for admin usersgetCurrentUserRoleAPI and treat both teachers and admins as instructorsgetCurrentUserRole- gets the current user's rolesearchUsers- searches and returns enriched user data (admin-only)updateUserRole- updates user roles with validation (admin-only)/adminrouteHow to test?
/adminto access user managementWhy make this change?
This enables proper user role management within the application, allowing administrators to promote users to teachers or other admins without requiring direct database access. The role-based access control ensures only authorized users can modify permissions, while the search functionality makes it easy to find and manage users at scale.
