Filter BTC-style sum-vout rewards to pool address for RVN/RTM/BTRM/XNA

[MoneroOcean]

Motivation

• BTC-style sum-vout reward accounting for some Raven-like ports was summing every coinbase output value as the block reward, which inflates the pool-creditable reward when coinbase enforces mandatory third-party outputs (masternodes/treasury/dev-fund).
• The intended behavior for pool-backed ports is to only count outputs payable to the pool wallet (or ignore configured addresses), so miners are not over-credited from pool reserves.

Description

• Added getBtcVoutAddresses(vout) helper and updated parseBtcReward to accept a poolAddress argument and to respect a new rewardPoolAddressOnly flag so that sum-vout mode can skip outputs not paid to the configured pool address and still honor rewardIgnoreAddress when present (lib/coins/core/factories.js).
• Changed createBtcRpc to pass ctx.runtime.getPoolAddress(ctx.profile) into parseBtcReward when resolving block headers so reward calculation can be pool-address aware (lib/coins/core/factories.js).
• Enabled rewardPoolAddressOnly: true for the affected profiles RVN, XNA, RTM, and BTRM so those ports use pool-address-only summation (lib/coins/rvn.js, lib/coins/xna.js, lib/coins/rtm.js, lib/coins/btrm.js).
• Added a regression test that asserts third-party coinbase outputs are ignored while multiple pool-address outputs are summed into the reported reward (tests/pool/coin/basics.js).

Testing

• Performed static syntax checks with node --check across the changed modules which completed successfully.
• Executed a targeted Node.js snippet exercising the new reward accounting path which validated the corrected reward (succeeded).
• Ran the package test harness invocation node --require ./tests/common/test_output_buffer.js --test ... tests/pool/coin/basics.js but it failed to run due to missing test dependencies (protocol-buffers module not installed) and therefore the full test suite was not executed.
• Attempted npm install to provision test deps but it failed due to registry access returning 403 Forbidden for crypto-js, preventing full automated test execution in this environment.
