fix: remove duplicate move_schematic_component tool registration and add regression test

The PR added a second server.tool("move_schematic_component", ...) at line 1127
without removing the original registration at line 722, causing the server to
fail on startup with "Tool move_schematic_component is already registered".

Also adds tests/test_ts_tool_registry.py which scans all src/tools/**/*.ts files
for duplicate server.tool() names so this class of bug is caught automatically.
