docs(1.7.122): curate release notes and add the in-app What's New block

Leads with what changes for the operator: app screens now require the node
password across LAN, Tailscale, mesh and Tor; the wallet/protocol ports that
must stay open stayed open; the mesh leak found during on-node verification;
nodes repairing their own legacy containers; and the signing-key rotation.
Known gaps disclosed, including the eleven still-undeclared ports and that
non-browser clients will now meet the login page.

The new block uses <strong> rather than the literal ** markers in earlier
entries, which render as asterisks in the modal.
