feat: index PoRep Market as first-class

[rvagg]

PoRep Market (FIDL's "cold storage") is the largest non-FWSS operator on FilecoinPay, but was unattributable because it deploys one Validator per deal. This change indexes PoRepMarket, ValidatorFactory, SPRegistry (a dedicated fork), and SLIOracle (mainnet V1) into porep_* tables, bridged to fp_* via porep_rail_id_updated (rail_id) and porep_proxy_created (operator). ABIs vendored from fidlabs/porep-market@8a20c1a.

Also:

• sql-validator: allow read-only stats aggregates, from watching what agents reach for (stddev, variance, percentile_cont/disc, mode, corr, covar)
• system-context: name PoRep Market and Storacha's wind-down, fix per-token decimals (axlUSDC is 6-dec) across aggregate recipes

Pull request overview

Adds PoRep Market (FIDL’s “cold storage”) as a first-class indexed service in the observer by introducing new porep_* event tables and Ponder handlers/contracts, and updates query guidance + SQL validation to better support cross-operator analytics (including mixed-token decimals and additional statistical aggregates).

Changes:

• Index PoRep Market V1 (Market, ValidatorFactory, SPRegistry, SLIOracle) into new porep_* tables and wire contracts into both mainnet and calibnet Ponder configs.
• Expand the SQL validator allow-list to include common statistical + ordered-set aggregates, with tests verifying WITHIN GROUP doesn’t bypass validation.
• Update system context to reflect PoRep attribution/bridging, per-token decimals (not universally 18), and Storacha being wound down.
