Description

Implemented an Estimated Reading Time feature for course content and notes.

The feature automatically calculates reading time based on the content's word count and displays it below the course/chapter title. This helps students estimate the time required to complete a topic before they start reading.

Resolved merge conflicts with upstream/main. Both the BookmarkButton and the estimated reading time feature are preserved.

@SamruddhiPatil0078 Thanks for working on this.

One thing to note: contributors are expected to wait for approval/assignment before starting work on an issue. Since this is your first contribution and the feature makes sense, I'll let it pass this time. Please follow the workflow going forward.

As for the implementation, I think the placement can be improved a bit. It may fit better right after the Course Outline heading or alongside the module/chapter title rather than below it.

Try a couple of placement options and see what feels more natural with the existing layout. Once updated, feel free to request another review.

I have updated the layout so the Reading Time indicator now sits right alongside the module/chapter title as requested!
