Fixed reset button behavior to match reset all functionality:
## 🔄 Reset Button Enhancement
- **Before**: Only cleared staged changes, kept current modified content
- **After**: Resets section to original content like "Reset All" function does
## 🎯 Consistent Behavior
- **Reset Button**: Now calls `sectionManager.resetSection()` for complete reset
- **Reset All**: Already used `resetSection()` for each section
- **Result**: Both reset functions now have identical behavior
## 🚀 Implementation Details
- **Section Reset**: Calls `resetSection()` to restore original markdown content
- **DOM Update**: Immediately updates display with `updateSectionContent()`
- **Staging State**: Updates staging state to reflect original content values
- **Preview Update**: Resets image preview and alt text input to original values
- **Change Indicator**: Clears "unsaved changes" warning
## 📝 Reset Button Workflow (New)
1. **Reset Section**: Restore section to original content and state
2. **Update Display**: Show original content immediately in document
3. **Parse Original**: Extract original image source and alt text
4. **Update Staging**: Set staging state to reflect original values
5. **Clear Changes**: Remove any staged modifications
6. **Update UI**: Reset preview and form inputs to original values
## ✅ User Experience
- **Consistent**: Reset button behavior now matches user expectations
- **Complete**: Resets everything back to original (not just current changes)
- **Immediate**: Users see original content restored right away
- **Reliable**: Works the same way as "Reset All" function
Added comprehensive test suite with 4 tests covering complete reset functionality.
Reset button now provides true "revert to original" behavior.
