Knowit 61fd3ff072 tools/epro2/kicad: fix two --all crashes found running the other 4 Pro projects
Running the new --all on the remaining 4 Pro projects (X86 motherboard,
220V power supply, Taishan Pi, Liangshan Pi) surfaced two crash modes
not covered by ESP-VoCat:

1. Odd inner-layer count → KiCad rejects the file at load with
   "3 is not a valid layer count". The 220V power boards have one
   used inner SIGNAL layer (3 copper total: F.Cu / In1.Cu / B.Cu),
   but KiCad requires an even copper count. Fixed pcb_writer to pad
   with one empty inner layer when the inner count is odd, so the
   total stays even (2, 4, 6, ...).

2. Two BOARDs sharing the same META.title — twin "显示板" boards in
   the 220V power project — landed in the same project directory
   and the second silently overwrote the first's .kicad_sch /
   .kicad_pcb / .kicad_pro. Fixed --all to detect title collisions
   and suffix every colliding basename with the BOARD uuid prefix
   (so both '显示板' boards become '显示板_52e8cc76' and
   '显示板_55d32906' rather than one quietly winning).

71 → 73 unit tests pass (test_odd_inner_signal_count_padded_to_even_total
+ test_duplicate_board_titles_get_distinct_basenames).

Tangentially noted while running this: Taishan Pi and Liangshan Pi are
Pro 2.x JSON, not EPRO2 streams — our replay layer reads the files but
doesn't decode docType, so SCH/PCB grouping returns nothing. Pro 2.x
needs a separate writer; out of scope for this commit.

"""CLI: convert EPRO2 SCH_PAGE docs to KiCad ``.kicad_sch`` files.
Usage:
uv run python -m tools.epro2.kicad <project_dir> --doc <sch_uuid> --out <dir>
uv run python -m tools.epro2.kicad <project_dir> --all-sch --out <dir>
uv run python -m tools.epro2.kicad <project_dir> --all-sch --flat --out <dir>
By default ``--all-sch`` produces a hierarchical project: pages are grouped
by their parent SCH (``META.schematic``) and each group gets a directory
with a root ``.kicad_sch`` plus its child pages. ``kicad-cli sch erc`` on
the root then resolves cross-page nets via ``(global_label)``. Pass
``--flat`` to fall back to one file per page in a single directory (the
old behaviour, still useful when you only care about a single page).
