Phase 1 pricing recalibration. The legacy formula
`price = (n / 6000)²` produced ~$25/GB at the lower stable boundary
and ~$0/GB when nodes were empty (with only a 1-wei sentinel floor) —
both unreasonable for the current ~\$0.10/ANT token price.
New formula:
price_per_chunk_ANT(n) = BASELINE + K × (n / D)²
with BASELINE = 0.00390625 ANT (spam barrier at empty), K = 0.03515625
ANT (re-anchored coefficient), and D = 6000 (unchanged). The non-zero
baseline removes the need for the legacy MIN_PRICE_WEI = 1 sentinel.
