fix(modules): guard the portal's nav icon, resolve MODULES_DIR absolutely
Both found by the §7.7 browser smoke, running the slice-3 pair together, and neither is visible to any test in either repo. `PlayerPortalLayout` rendered `<n.icon />` unguarded while `AdminLayout` guarded its equivalent. `icon` is optional in the nav contract, and every core row in that sidebar has always had one — so the difference cost nothing until a module registered a row without, and then it was not a missing glyph, it was React error #130 and a blank player portal. Guarded now, like its neighbour. `MODULES_DIR` is resolved absolute. `resolveClient` checks containment by comparing an absolute `path.resolve(dir, entry)` against the module directory, so a RELATIVE `MODULES_DIR` — which is what §7.7's own recipe produces when run from `server/` — failed every module with "client.entry escapes the module directory". A perfectly-placed entry, and a message pointing at the module. Co-Authored-By: Claude <noreply@anthropic.com>
