Subject: [PATCH] fix: Remove persistent HTML comment from manage event page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Modified page-manage-event.php template to access raw post content directly
- Added comprehensive regex patterns to strip all variations of wp:shortcode comments
- Disabled the_content filter in HVAC_Manage_Event class to prevent conflicts
- Added client-side JavaScript fallback to remove any remaining HTML comments
- Created cache clearing script for troubleshooting

The issue was that apply_filters('the_content') was potentially re-adding
content after we stripped the HTML comments. Now we bypass all filters
and process the raw content directly.
