Task 2: Create Dedicated Replication Documentation Section

[akc2267]

This will certainly make for a good document, that can work along side the existing P2P docs.

Issue: R1, R2, R4 struggled with replication setup and concepts

Actions:
Create a dedicated "Data Replication" section with:

• Overview of replication types (P2P pubsub vs replicator)
• When to use each type
• Fred recently made an internal doc that includes a bunch of notes on this, can be used to create an external doc. https://github.com/sourcenetwork/internal-docs/blob/main/DefraDB/WebsiteDocs/Drafts/Different%20ways%20to%20sync%20with%20DefraDB.md
• Step-by-step setup guides for each
• Platform-specific instructions (PowerShell, bash, etc.)
• Troubleshooting peer connectivity issues
• Key management during replication
  Add diagrams showing replication architecture
  Include working examples for common scenarios
  Document automatic peer discovery vs manual connection
