Add a live P2Pool mining section to the homepage

A new #mining section invites visitors to mine on p2pool.eom.dev and shows
live node/sidechain/network hashrate, connected miners and shares from the
same-origin /p2pool/stats.json summary published by ansible-role-monero.
The stats load progressively: static placeholders and join instructions
remain when the endpoint is unavailable (including in the local preview
and on the onion mirror).

+### Live mining stats
+
+The **Mine Monero with us** section (`#mining`) uses
+[htdocs/static/p2pool-stats.mjs](htdocs/static/p2pool-stats.mjs) to read
+`/p2pool/stats.json`. That same-origin path is not part of this repository: the
+[ansible-role-monero](https://gitea.eom.dev/DevOps/ansible-role-monero) stats
+sidecar publishes it through an Ingress on the website host. The summary carries
+only aggregate numbers (node, sidechain and network hashrate, connected miners,
+shares) and never miner IPs or wallets. The module accepts only those numeric
+fields, writes plain text into fixed `[data-stat]` cells, limits responses to
+64 KiB with a 10-second timeout, and refreshes every minute while the page is
+visible. When the endpoint is missing (local preview, onion mirror, P2Pool
+restarting) the `—` placeholders and join instructions stay in place.
 No Creator Launch project or service offer is involved.
