Add API key generation instructions linking to console.solidrust.ai #9

Description

Documentation references getting an API key from console.solidrust.ai but doesn't provide clear instructions on how to generate one. New users need step-by-step guidance.

Current State

Quick Start page says:

Prerequisites: An API key from console.solidrust.ai

But provides no instructions on:

1. How to sign up
2. Where to find API key generation
3. How to manage/rotate keys

Proposed Addition

Create a new page: src/content/docs/getting-started/api-keys.md

Content Should Include:

1. Getting Started

   • Link to console.solidrust.ai
   • Sign up process
   • Initial navigation

2. Generating API Keys

   • Step-by-step with screenshots (optional)
   • Key naming best practices
   • Where keys are displayed

3. Security Best Practices

   • Never commit keys to git
   • Use environment variables
   • Key rotation schedule

4. Managing Keys

   • Viewing existing keys
   • Revoking keys
   • Regenerating keys

5. Troubleshooting

   • 401 Unauthorized errors
   • Key validation issues

Acceptance Criteria

• New API Keys documentation page created
• Added to "Getting Started" section in sidebar
• Linked from quickstart.md prerequisites
• Includes security best practices
• Clear, actionable instructions

Priority

MEDIUM - Helps onboarding, but users can currently figure it out through the console UI.
