Retrieves a paginated list of active Avalanche Primary Network validator nodes associated with the
supplied P-Chain wallet addresses — nodes the addresses delegate to, or own (created the validator).

A node is included when at least one of the supplied addresses:

• is the validator owner — matched against the node's ownerAddress (the validation-reward /
  stake-return owner; in the CDAO staking flow this is the walletAddress used at
  /avalanche/transactions/stake), or
• has an active delegation on the node — matched against the delegation's reward owner, which in
  the CDAO delegation flow defaults to the delegating wallet itself.

Only currently active validators are returned (validation period ongoing; pending and completed
positions are excluded). Each node appears once even if several supplied addresses — or both roles —
relate to it. Items share the same shape as GET /avalanche/validators plus wallet-scoped fields
(ownerAddress, walletDelegatedAvax, walletDelegationEndTime): compare ownerAddress against the
queried addresses to distinguish nodes the caller owns from nodes the caller delegates to, and read
walletDelegatedAvax / walletDelegationEndTime for the caller's own delegation on each node.

Typical uses: rendering the "my staking" screen in a custodian wallet, and pre-checking positions
before delegating more via /avalanche/transactions/delegate.
