Update Tailscale blog post for v3.0.0 add-on changes

[atj4me]

The Issue

The Tailscale DDEV add-on blog post was outdated and no longer accurately reflected the current v3.0.0 architecture, commands, and features. The post contained:

• Incorrect architecture description (separate container vs userspace networking)
• Outdated command structure and workflow
• Missing new authentication options
• No uninstall instructions
• No mention of the significant v3.0.0 updates

How This PR Solves The Issue

This PR comprehensively updates the blog post to reflect all v3.0.0 changes:

• Architecture: Updated description to reflect userspace networking approach with better macOS compatibility
• Authentication: Added alternative interactive authentication method using ddev tailscale login
• Commands: Updated to new simplified command structure (ddev tailscale share, ddev tailscale stop, etc.)
• Workflow: Added requirement to explicitly start sharing (no longer auto-connects)
• Documentation: Added uninstall instructions and mention of ddev tailscale help command
• Version awareness: Added prominent update notice linking to v3.0.0 migration instructions
• Clarity: Clarified differences with ddev share (ngrok requirement)
• Metadata: Updated modified date and summary to indicate v3.0.0 compatibility

Manual Testing Instructions

1. Review the updated blog post content for accuracy
2. Verify all links are working and point to correct documentation
3. Check that code examples use the correct v3.0.0 command syntax
