Get your own reward scoring inputs for one epoch

What the maker-reward formula saw for YOU on one distribution day (LIQ-8): qualifying volume, the sampled spread/depth/uptime terms under v2, the quality actually applied after any floor, the resulting weight, and any exclusions with their reasons. A shadow epoch returns both the row that paid and the dark `v2-shadow` row for the same market. Scoped to the caller — it never returns another maker's inputs.
