Deduplicate platform docs and add misuse warnings

Move platform mechanics (points breakdown, link limits, submission UI)
to course-management-platform as single source of truth. Course-specific
pages now link to platform pages instead of repeating details.

Add learning in public misuse warnings to DE and ML zoomcamp pages.

+# Learning in Public
+
+The course management platform rewards you for sharing your learning journey publicly. When submitting homework, projects, or peer reviews, you can include links to social media posts about what you learned - each link earns extra points on the [leaderboard]({{ '/courses/course-management-platform/leaderboard/' | relative_url }}).
+
+## How It Works
+
+When you submit homework, a project, or a peer review, you'll find a "Learning in public links" section in the submission form.
+
+<img src="{{ '/assets/images/course-management-platform/learning-in-public-links.png' | relative_url }}" alt="Learning in public links section in course platform" width="80%">
+
+Add links to your social media posts about what you learned. Each link earns 1 extra point on the leaderboard.
+
+Link limits per submission type:
+
+- Homework submissions - up to 7 links
+- Project submissions - up to 14 links
+- Peer reviews - up to 2 links
+
+## What Counts as a Valid Link
+
+Valid links are your personal social media posts where you share your progress, insights, or experiences from the course. These include posts on:
+
+- LinkedIn
+- X (Twitter)
+- BlueSky
+- Medium, Dev.to, Hashnode, or other blogging platforms
+- Personal blogs or websites
+
+Each link should be a post you created yourself about what you are learning in the course.
+
+## What Does Not Count
+
+Links that are not your personal posts about the course do not count. Examples of invalid links:
+
+- Documentation pages (e.g. Google Cloud docs, W3Schools)
+- YouTube videos from other people
+- Random articles or tutorials found on the internet
+- Course materials or lecture links
+- Links to tools or software websites
+
+The screenshot below shows an example of misuse - the submitted links are documentation pages and YouTube videos instead of the student's own social media posts:
+
+<img src="{{ '/assets/images/course-management-platform/learning-in-public-misuse.png' | relative_url }}" alt="Example of learning in public misuse - random links instead of personal posts" width="80%">
+
+## Misuse Policy
+
+Submitting links that are not your personal social media posts is against the rules. If a course participant is found misusing the system:
+
+- All points earned from "Learning in Public" will be removed from their account
+- The ability to earn "Learning in Public" points will be permanently disabled for them
+- They can still participate in the course and earn points from homework, projects, and peer reviews
+
+We encourage everyone to actually practice learning in public because it benefits you directly - it helps reinforce what you learned, builds your professional network, and creates a portfolio of your skills. But submitting random links just for points defeats the purpose.
+
+## Reporting Misuse
+
+If you come across anyone on the leaderboard who is misusing this system by posting links that are not their personal posts about what they are learning in the course, please report it in the course Slack channel.

 The leaderboard creates friendly competition and encourages consistent participation throughout the course.
 
+Only submit links to your own social media posts about the course when earning learning in public points. Submitting unrelated links will result in losing all learning in public points.

 This is totally optional. The leaderboard is just for fun. You can completely ignore it and still get everything you need from this course. The main goal is for you to learn data engineering.

 Earning your ML Zoomcamp certificate requires completing a specific combination of projects rather than achieving a particular grade. You must **pass 2 out of 3 available projects**, giving you flexibility in choosing your path. You can complete either the midterm project plus the final capstone project, or the final capstone project plus a second capstone project.
 
-For each project you submit, you're required to **complete peer reviews** by evaluating 3 of your fellow students' projects. This peer review process is mandatory and helps reinforce your learning while contributing to the community.

 Consider writing blog posts about concepts you've mastered or challenges you've overcome. Examples include "Understanding Cross-Validation in Module 4" or "My Journey Deploying a FastAPI Model." Posts about struggles like "3 Deployment Failures That Taught Me Docker Basics" are often more valuable than success stories. When you feel confident in a topic, answer questions in Slack—teaching others solidifies your own knowledge.
