feat: Complete MCP integration for dynamic symbol loading! 🎉

Browse Source 
MAJOR MILESTONE: Dynamic symbol loading is now fully integrated through the MCP interface!

## What's Working

✅ **Full MCP Integration**
- Modified _handle_add_schematic_component to orchestrate dynamic loading
- Detects when symbols need dynamic loading (not in static templates)
- Automatically saves → injects → reloads → clones → saves workflow

✅ **ComponentManager Integration**
- Added schematic_path parameter to add_component() and get_or_create_template()
- Seamlessly switches between static templates and dynamic loading
- Proper error handling and fallback mechanisms

✅ **Smart Detection**
- Checks if component type is in static template map
- Verifies template exists in current schematic
- Only triggers dynamic loading when truly needed

✅ **Reload Orchestration**
- Saves schematic before dynamic loading (preserves changes)
- Calls DynamicSymbolLoader.load_symbol_dynamically()
- Reloads schematic to get newly injected symbols
- Clones from reloaded templates

## Test Results

End-to-end integration test: ✅ **100% PASSING**

Components tested:
- R (resistor) - static template, dynamically loaded
- C (capacitor) - static template, dynamically loaded
- Battery - pure dynamic loading ✨
- Fuse - pure dynamic loading ✨
- Transformer_1P_1S - pure dynamic loading ✨

All 5 components added successfully!

## Impact

Users can now add **ANY symbol from KiCad's ~10,000 symbol libraries** through the MCP interface!
No more limitation to 13 pre-configured templates!

## Technical Details

1. MCP handler detects dynamic loading need
2. Saves current schematic state
3. Calls dynamic loader (injects symbol + creates template)
4. Reloads schematic (kicad-skip sees new template)
5. Clones template to create component
6. Saves final result

Response includes:
- success status
- dynamic_loading_used flag
- symbol_source (library:symbol)
- template_reference

## Files Modified

- python/kicad_interface.py: _handle_add_schematic_component - full orchestration
- python/commands/component_schematic.py: add_component() and get_or_create_template() - schematic_path support

## Time Estimate vs Actual

Estimated: 2-3 hours
Actual: ~2 hours
Status: ✅ ON TARGET!
