Chuck f412350110 Fix/fonts loading error (#148)
* fix(docs): Add trailing newlines to documentation files

* fix(web): Resolve font configuration loading error on first page load

- Remove ineffective DOMContentLoaded listener from fonts partial (loads via HTMX after main page DOMContentLoaded)
- Add proper HTMX event handling with htmx:afterSettle for reliable initialization
- Add duplicate initialization protection flag
- Improve error handling with response validation and clearer error messages
- Add fallback initialization check for edge cases
- Ensure DOM elements exist before attempting initialization

Fixes issue where 'Error loading font configuration' appeared on first web UI load when opening fonts tab.
