fix: Ensure media header templates appear in template selector

- Remove format-based filtering that was preventing media templates from showing
- Add robust error handling for template loading without console statements
- Include comprehensive validation for template properties
- Add debug helper method to troubleshoot template visibility issues

Previously, templates with media headers (IMAGE, VIDEO, DOCUMENT) were being
filtered out even though we removed format restrictions. This fix ensures
all approved templates are visible in the template selector regardless of
their media format.
