fix: update templates to KiCAD 9 format + remove corrupt _TEMPLATE_ blocks

Browse Source 
Verified by live test: created a fresh schematic via MCP, result shows
format version 20250114, 0 _TEMPLATE_ hits, 0 (lib_id -100) hits, 24
real components placed cleanly.

--- Format version bump (20230121 KiCAD 7 -> 20250114 KiCAD 9) ---
Files: python/templates/*.kicad_sch, python/commands/project.py,
       python/commands/schematic.py

Root cause: the MCP server targets KiCAD 9 exclusively - pcbnew.pyd is
compiled for KiCAD 9.0 / Python 3.11.5, and server.ts explicitly selects
the KiCAD 9 bundled Python on Windows. Generating new schematics with a
2-year-old format tag caused a spurious 'This file was created with an
older KiCAD version' warning on every newly created schematic.

--- Remove corrupt _TEMPLATE_* placed-symbol blocks ---
File: python/templates/template_with_symbols_expanded.kicad_sch

Root cause: the expanded template was generated by the old sexpdata
serializer (same corruption PR #40 fixed for DynamicSymbolLoader add-path).
The serializer converted the string 'Device:R' to integer -100, producing
(lib_id -100) instead of (lib_id Device:R). KiCAD cannot resolve an
integer as a library reference and crashes with a null-pointer when the
user attempts to select these symbols. They appeared as grey _TEMPLATE_R?,
_TEMPLATE_C?, _TEMPLATE_U_REG? etc. ~5000mm off-sheet - invisible during
normal work but triggering a crash on accidental box-select.

Discovered via live testing on a real JLCPCB/KiCAD 9 project.
