feat: enhance Mind Map into study planner with academic tracking system

[bansalrujul07]

📌 Description

This PR improves the existing Mind Map feature in StudyMatePlus by transforming it from a generic diagram editor into a more student-focused study planning tool. Previously, the Mind Map only acted as a visual node editor without any academic structure. This update introduces study-oriented metadata to each node so students can better organize and track their syllabus. Now each node can represent real study components like subjects, units, topics, and subtopics along with progress tracking and priority levels. The goal is to make the Mind Map more useful for exam preparation, revision planning, and syllabus tracking while keeping the UI and overall structure unchanged.
