fix(recipes): show initialization screen and auto-reload during first scan

The recipes page always rendered with is_initializing=False, so a cold
start displayed an empty grid that never updated until a manual refresh.
Mirror the model pages: gate render_page on the scanner state, broadcast
init progress from RecipeScanner (including a completion message, and a
failure fallback so the page never stalls), and teach initialization.js
to detect the /loras/recipes page before the generic /loras match.
