fix: correct TEC shortcode format for event editing form population

- Update includes/class-hvac-shortcodes.php:277 to use [tribe_community_events view="submission_form"]
- Update templates/page-manage-event.php:83 to use correct TEC shortcode format
- Fixes issue where event edit forms appeared blank instead of populated with existing data
- TEC submission_form view automatically detects event_id URL parameters for editing
- Enables proper event creation and editing functionality for trainers
