prepare BOM

Prepared a draft BOM CSV with 12 unique line items and 28 total instances: https://cdn2.flux.ai/flux-comment-files/files/commentFileId-a8deebbe9143ebc2b629fb20e0712afa8b7785d2785d5091b3deb2f60a96756f.csv?GoogleAccessId=agent-chat-sa-967d763%40graviton-mvp.iam.gserviceaccount.com&Expires=4932307493&Signature=aJWzBbHwZHkl%2BmnICiO9rNTpIs9tZsd2wjmpDuccAJBpy1E%2BsaQfMoOJoChjS%2BHu094KoIg3ehDcrOJHtUSVbGvQNPuBu%2FeqwpyUWkV62mw7%2FoY2Uwz4voWcjYYNVpBnrj10EV77%2Fltxe8FTfgeGsiDOpGtl1VJg5tfV0TTHxv8c5okcwTLhWnnztGAEJkrxMm5yzG3DlkKFsUNcIRSLShGsNN5ly%2FqkKuMgj%2ByoQw9TNecypM%2FCKT8ABxbuKMhZ3mFlH6HagLHpznqD%2BAwS%2F0kFDFuSvlh9j9YWkBlrEqlu3JBXQ7OYDyQr3MmQmA2B8V5Ah7CVEu1GNehX%2FSrNXw%3D%3D. Note: the design still has 25 airwire DRC errors and 1 overlapping-copper error, so this is a draft sourcing BOM rather than a manufacturing-ready release BOM.
