Subject: [PATCH] fix(theseus/home): dynamic search-engine name in placeholder

Home page's search-box placeholder was hardcoded "Search the web
(DuckDuckGo)", but the browser's default engine has been Startpage
for a while and any user can switch to another in Settings. The
"DuckDuckGo" claim then contradicted the actual engine that would
run the query (main.js routes through settings.searchEngine).

Fix: placeholder starts as plain "Search the web" and populates on
load with "Search the web with <engine.name>" via a new
window.home.getEngines() IPC (reuses the existing search-engines
handler). Silently no-ops if the preload isn't bound.

Also swapped the never-fires no-preload fallback URL from
duckduckgo.com to startpage.com so it matches Theseus's own default.
