Show V2 vaults in market supplying vaults

[antoncoding]

Context\n\nMorpho API market.supplyingVaults only returns Morpho-listed vault addresses. It does not include Monarch V2 vault adapters or parent V2 vault addresses, even when those adapters hold active Morpho Blue supply positions.\n\n## Goal\n\nShow V2 vaults as supplying vaults on market/list surfaces by using Monarch data.\n\n## Proposed approach\n\n- Use Monarch Adapter records to map adapter addresses to parent V2 vaults.\n- Use Monarch Position rows to find adapter accounts with active supplyShares > 0 per marketId and chainId.\n- Join adapter position rows back to Adapter.vaultAddress and vault metadata.\n- Scope fetching to market detail or visible market rows first to avoid global load.\n- Longer term, consider adding an indexer relationship/view such as AdapterPosition joining Position.user = Adapter.adapterAddress and Position.chainId = Adapter.chainId, so this becomes a single GraphQL query.\n\n## Acceptance criteria\n\n- Market supplying-vault UI can include Morpho-listed vaults and Monarch V2 vaults.\n- V2 entries clearly show the vault and adapter relationship.\n- Existing Morpho-listed vault behavior is preserved.\n- Broad market lists avoid fetching all adapter positions globally unless cached or paginated safely.
