fix: simplify FORD configuration to prevent deployment hangs (#203)

## Summary
- Simplified FORD metadata configuration to resolve GitHub Actions
deployment timeouts
- Removed redundant configuration options that were causing deployment
hangs
- Fixed media_dir path to match actual directory structure (./media
instead of ./doc/media)

## Problem
The GitHub Actions docs deployment workflow was hanging/timing out
consistently due to complex FORD configuration. Two consecutive
deployments got stuck in "pending" state for over 10 minutes.

## Solution
Simplified the FORD configuration by:
- Removing redundant URL configurations that FORD doesn't need for basic
operation
- Fixing media_dir path to point to actual media location
- Keeping only essential configuration options

## Test Plan
- [ ] Verify deployment completes without hanging
- [ ] Check that examples are properly included in generated
documentation
- [ ] Confirm media files are accessible

This addresses the immediate deployment issue preventing examples from
appearing on the live site.
