Update installation script to show API key link and use current endpoint

[Copilot]

The installation script needed to display the Google AI Studio URL when prompting for API keys, and the post-installation test command referenced a deprecated endpoint.

Changes

• Display API key URL: Echo https://aistudio.google.com/app/api-keys before prompting for Gemini API key
• Update test endpoint: Changed post-installation curl example from /create_profile to /analyze_and_profile
• Correct URL path: Fixed /app/apikey → /app/api-keys in all references

Before:

# --- Gemini API Key ---
# Get your free API key at: https://aistudio.google.com/app/apikey
read -r -p "Enter your Google Gemini API Key: " GEMINI_KEY

After:

# --- Gemini API Key ---
# Get your free API key at: https://aistudio.google.com/app/api-keys
echo "Get your free API key at: https://aistudio.google.com/app/api-keys"
read -r -p "Enter your Google Gemini API Key: " GEMINI_KEY

Test command updated:

curl -X POST -F 'coffee_info=System Test' -F 'user_prefs=Default' \
  http://$PI_IP:8000/analyze_and_profile

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
