Switch lamps to internal IDs; EAN becomes optional metadata

Directories rename from bare EANs to L0001..L0010 (measurement order).
metrics.json gains an ean field, and a rated block with advertised
values (flux, CCT, power, lifetime) where already documented, so the
site can show advertised-vs-measured deltas. One EAN can now cover
several lamp versions (variant field) and unbranded lamps need no
barcode.
