chore(release): v1.8.9-alpha prep — What's New block + version bumps

The release gate requires the freshly-built bundle to embed the new
version, and the version reaches the bundle through the What's New
modal in AccountInfoSection — there was no v1.8.9-alpha block yet, so
create-release.sh correctly refused to ship a bundle that looked stale.
This adds the block (the user-facing summary of today's LND/HTTPS/
launcher/NPM/Portainer fixes) and carries the version bumps the
aborted run had already written (Cargo.toml, Cargo.lock, package.json,
package-lock), so the re-run starts from a clean tree.

Verified: npm run build now produces assets containing 1.8.9-alpha
(Settings chunk), i.e. the exact check the script runs passes.
