fix: Update schematic format to KiCAD 9 and fix invalid UUIDs (#37)

Browse Source 
- Update schematic version from 20230121 (KiCAD 7) to 20240101 (KiCAD 9)
- Replace invalid all-zeros UUIDs in template files with valid UUIDs
- Add post-copy UUID regeneration to ensure each project gets unique UUID
- Add UTF-8 encoding and Unix line endings for cross-platform compatibility

Fixes the root cause where templates were copied with invalid UUIDs and
outdated version format, causing KiCAD 9.0.x to reject the schematic files.
