chore(dex): decommission 3 unused hidden-leaf spells

[a-monteiro]

Decommissions 3 unused hidden-leaf spells in dex as part of the compute-optimization quick wins.

Each spell is hidden (hide_spells() -> dune.visible=false), a leaf (no other dbt/sqlmesh model, exposure, or curated-data reference -- only its own schema tests; the dex.trades union consumes *_base_trades, not these per-project .trades views), and unused by customers (zero enterprise/paid queries over Jan-Jun 2026 in QES, below the negligible-free bar). Removed: paraswap_delta_v2_optimism.trades, gamma.uniswap_pools, odos_avalanche_c.trades.

Compute here is marginal (~0.03 CPU-hrs/day combined) -- this batch is hygiene/completeness; the real savings are in the daily and hourly batches.

The 4th candidate from CUR2-2855, zeroex_polygon.nft_fills (0.000 CPU-hrs/day), is deferred: its schema block is the anchor-definition source for the rest of zeroex_polygon_schema.yml, so removing it requires relocating 14 YAML anchors into surviving sibling models. Not worth the structural churn for zero compute savings; can be done separately if desired.

dbt parse is clean; surviving sibling models in the edited paraswap schema are byte-identical.

PR Summary

Low Risk
Deletes unused hidden models with no remaining dbt references; downstream dex.trades paths use other models, so impact is limited to stopping marginal scheduled builds.

Overview
Removes three hidden-leaf dbt spells from the dex subproject as compute/hygiene cleanup: the gamma.uniswap_pools union over Optimism Gamma pools, odos_avalanche_c.trades (legacy Spark aggregator spell marked prod_exclude), and paraswap_delta_v2_optimism.trades (thin wrapper around delta_v2_master).

Each deletion includes the matching _schema.yml entries (tests and column docs). Chain-specific models such as gamma_optimism_uniswap_pools and other Paraswap Optimism models are unchanged; only these unused surfaced tables go away.
