1.2.1: surface "Copy previous week" on the empty-week banner

The exact-copy-from-previous-week action already existed but was buried in the
magic-wand long-press context menu. Expose it as a visible secondary button on
the auto-assign banner (shown only when the previous week actually has a menu),
so users landing on a fresh week can one-tap copy last week's plan and then tweak
it. Confirms before overwriting a week that already has dishes.

- Extract requestCopyPreviousWeek() shared by the menu and the banner.
- Add week_copied_previous analytics (copied_slots + source: empty_banner|menu).
- Reuses the existing localized home_copy_previous_week string (all 6 languages).
