routes/index: use m.home_title() + pass undefined locale to findPosts

Title was hardcoded to the German string when I migrated the rest of
the site to paraglide — the rest of the site looked correct on /en/
because the localized meta came from the root route's head() which DID
use m.foo(). Index also passed 'de' literally to findPosts, ignoring
the request locale.
