Add comprehensive router/AP reliability blog post with industry statistics

[Copilot]

This PR adds a new internal blog post documenting industry statistics about home router and access point reliability issues in smart home network deployments.

New Content Added

Blog Post: documentation/docs/router-reliability-blog.md

• Comprehensive analysis of smart home network reliability challenges
• Industry statistics from three major research sources
• Structured troubleshooting and reliability section
• Arguments supporting closed access point deployments

Key Statistics Included

The blog post incorporates hard data from leading industry research:

• Parks Associates (2022): 60% of households require monthly router reboots; 41% of troubleshooting incidents resolved by rebooting
• Statista (2024): 1 in 4 households experience quarterly outages caused by routers; 35% of network failures linked to router performance
• Consumer Reports (2023): 30% of users blamed their router for network issues in the past 6 months

Documentation Structure

• Added summary statistics table for easy reference
• Organized content with clear sections covering introduction, data analysis, and conclusions
• Highlighted how statistics support closed AP reliability arguments
• Updated MkDocs navigation to include the new blog post
• Added reference link in main documentation index

The blog post provides compelling evidence that home routers are frequently the weak link in smart home deployments and presents a data-driven case for enterprise-grade closed access point systems.

This pull request was created as a result of the following prompt from Copilot chat.

Update the internal blog post to include hard data and industry statistics about how often home APs/routers are the problem in smart home network failures and troubleshooting. Add a section with:

• Parks Associates (2022): 60% reboot monthly, 41% of troubleshooting incidents resolved by rebooting.
• Statista (2024): 1 in 4 households have quarterly outages caused by router; 35% of failures linked to router.
• Consumer Reports (2023): 30% blamed router for issues in past 6 months.
  Include a summary table and highlight that these statistics support using a closed AP for reliability. Place the data in the troubleshooting/reliability section and make reference in the introduction or conclusion if relevant.
