satoshi 83d70b2636 Fix accelerator revenue impact always showing zero
The old approach compared coinbasevalue from two getblocktemplate
calls, but new mempool arrivals between calls masked the displacement
loss. Now uses a single template snapshot to find the marginal
(lowest fee-rate) transaction that would be displaced and reports
its fee as the revenue cost.

Transaction Accelerator
</h2>
<p class="explainer">
Boost a transaction's priority in your next block template using
<code>prioritisetransaction</code>. When your pool finds a block,
the boosted transaction will be included regardless of its real feerate.
</p>
<div class="info-box">
<p>
<strong>How it works:</strong> The boosted transaction takes the place of
the lowest-feerate transaction at the bottom of the block template. If the
mempool isn't full (all transactions already fit), there is <em>zero cost</em>.
</p>
<p>
<strong>Revenue impact:</strong> The server inspects the current block template to find
the marginal transaction &mdash; the lowest fee-rate tx that would be displaced by the
boosted one. Its fee is the revenue you sacrifice per block mined, shown after each boost.
</p>
<p>
Your pool: {formatHashrate(poolHashrate)} /
{formatHashrate(networkHashrate)} network
({poolShare > 0 ? `${(poolShare * 100).toFixed(6)}%` : "—"} of blocks).
