[WIP] Additions to readme

[Copilot]

Successfully added all requested sections to README.md for better user guidance and transparency.

• Add Server Requirements and Recommendation section
• Add Default login information section
• Add Affiliation statement
• Review and test that all sections integrate well with existing content

Completed Changes:

1. Server Requirements and Recommendation (Lines 13-25):

   • Added between intro and Quick start section
   • Includes hardware requirements and deployment recommendations
   • Links to official RustDesk documentation
   • Emphasizes dedicated server recommendation for install.sh

2. Default Login (Lines 309-320):

   • Added after Operations section, before Troubleshooting
   • Provides critical default admin credentials (admin/test1234)
   • Includes security recommendation to delete default account
   • Links to official RustDesk console documentation

3. Affiliation (Lines 347-351):

   • Added before License section
   • Clearly states no affiliation with RustDesk or Caddy
   • Provides transparency about repository relationship

All sections are properly formatted with markdown, include appropriate links to official documentation, and integrate seamlessly with the existing README structure.

Fixes #2.
