Replace isolated template previews with live collection reconstruction:
- Frontend now reconstructs collection container with all template variants
- Users click directly on rendered templates in proper CSS context
- Perfect preservation of grid/flex layouts and responsive behavior
- Simplified API: preview endpoint returns container_html + templates for frontend reconstruction
- Enhanced UX: WYSIWYG template selection shows exactly what will be added
- Removed redundant templates endpoint in favor of unified preview approach
Backend changes:
- Add GET /api/collections/{id}/preview endpoint
- Remove GET /api/collections/{id}/templates endpoint
- Return container HTML + templates for frontend reconstruction
Frontend changes:
- Replace isolated template modal with live collection preview
- Add generateLivePreview() method for container reconstruction
- Update CollectionManager to use preview API
- Add interactive CSS styling for template selection
This provides true contextual template selection where CSS inheritance,
grid layouts, and responsive design work perfectly in preview mode.
This commit addresses multiple collection management issues to improve user experience:
## Template Selection Modal Improvements
- Replace inline styles with CSS classes for reliable visual feedback
- Fix default template selection conflicts that showed multiple templates as selected
- Add styled template previews that show actual CSS styling differences
- Improve modal responsiveness and visual hierarchy
## Collection Item Creation Fixes
- Fix empty collection items with no content/height that were unclickable
- Preserve template placeholder content during item creation instead of clearing it
- Implement proper positioning system using GetMaxPosition to place new items at collection end
- Add position calculation logic to prevent new items from jumping to beginning
## Backend Positioning System
- Add GetMaxPosition method to all repository implementations (SQLite, PostgreSQL, HTTPClient)
- Update CreateCollectionItemFromTemplate to calculate correct position (maxPos + 1)
- Maintain reconstruction ordering by position ASC for consistent item placement
## Frontend Template Selection
- CSS class-based selection states replace problematic inline style manipulation
- Template previews now render actual HTML with real page styling
- Improved hover states and selection visual feedback
- Fixed auto-selection interference with user interaction
These changes ensure collection items appear in expected order and template selection
provides clear visual feedback with actual styling previews.
- Update collection manager to use data-collection-id instead of data-content-id
- Add safety checks to prevent undefined Map access in addItemControls
- Add validation in editor to only initialize collections with valid collection IDs

- Fix collection item position persistence through content edit cycles
- Add optimistic UI with rollback capability for better user experience
- Update sqlc queries to include last_edited_by fields in position updates
- Remove obsolete data-content-type attributes and unify naming conventions
