Pad-net compare strips leading slash and nested sheet path so /ESP32_EN
matches ESP32_EN. If every mismatch is only that prefix, emit PE-LAY-003
once instead of per-pad reconnect errors.
A container rebuild left Emmaforo status=running with no process, so
PCB start kept 409. Heal on GET now matches placement/PCB: complete if
report.json exists, otherwise error.
update_project used meta.user_id for the path, so JWT projects that still
have user_id=local never persisted pcb_status=queued and the PCB worker
exited as draft. Point writes at the prefix used to read the project.
