Add list_user_activity_stream() function to vvcanvas

[Copilot]

Implements a new function to fetch the recent activity feed for a user from the Canvas LMS API.

Changes Made

New Function: list_user_activity_stream(canvas, user_id = "self", per_page = 100, ...)

• Endpoint: GET /api/v1/users/:user_id/activity_stream
• Default Behavior: Uses "self" for the current authenticated user when user_id is not provided
• Pagination: Supports per_page parameter with sensible default of 100
• Extensibility: Accepts additional parameters via ... for future Canvas API features
• Returns: List of activity stream objects (Canvas Stories) representing recent user activities

Usage Examples

# Get activity stream for the authenticated user
canvas <- canvas_authenticate()
activities <- list_user_activity_stream(canvas)

# Get activity stream for a specific user
activities <- list_user_activity_stream(canvas, user_id = "12345")

# Get activity stream with custom pagination
activities <- list_user_activity_stream(canvas, per_page = 50)

Package Integration

• Documentation: Complete Roxygen2 documentation with usage examples and API reference
• TODO.md: Updated to mark activity stream endpoints as completed
• pkgdown: Added new "Users" section with the function registered for documentation site
• Consistency: Follows existing package patterns for authentication, error handling, and parameter conventions

Technical Details

• Uses standard httr::GET() with proper query parameter handling
• Implements consistent error checking for HTTP status codes
• Returns parsed JSON response using jsonlite::fromJSON(flatten = TRUE)
• Follows the same parameter handling pattern as other functions in the package

The function integrates seamlessly with the existing vvcanvas architecture and provides users with access to Canvas activity streams for monitoring recent user interactions across courses.

Fixes #32.

@copilot use the new paginate function see other functions how to use it

Updated the list_user_activity_stream() function to use the new paginate function following the same pattern as other functions in the package. The function now:

• Uses paginate(response, canvas$api_key) instead of manual pagination
• Returns a data frame instead of a list for consistency
• Automatically retrieves all pages of results
• Follows the same pattern as get_course_enrollments, get_course_students, etc.
