Fix empty Zombie-Apokalypse list and translate its items to German

Migration 002 looked item groups and items up by their English sample-data
names, so on a database with its own German groups the hidden activity got
no items. Migration 003 rebuilds the list: items go into their German group
or, if it is missing, a new "Zombie-Abwehr" group; existing items are
reused; the English items 002 created are removed. It is safe to rerun.

Adds a few more items (Twinkies, Knoblauch, Gartenzwerg zur Ablenkung, ...)
and renames the activity to Zombie-Apokalypse in the group Überleben.

The progress nag no longer lowercases item names, which mangled German
nouns ("the stirnlampe").

 - **Per-mapping quantities** — Each activity-to-item mapping carries a quantity. Items needed in multiples (e.g. 2× Water bottle) are rendered with a leading multiplier, and merging across activities keeps the largest required quantity.
 - **Grouped items** — Items are organised into logical categories (Clothing, Shelter, Navigation, Medical, Water & Food, Safety Gear) for easy scanning.
 - **Interactive checklist** — Click any item to mark it as packed. Checked items are visually struck through and a progress bar updates in real time. Ticks are stored in the browser under the list's hash and restored on the next visit; a **Reset** button appears once something is ticked. Nothing is sent to the server, so each device keeps its own progress, and a browser with site data blocked simply falls back to not remembering.
-- **Nagging progress messages** — A line under the progress bar comments on how the packing is going, from *"The tent won't pack itself."* at zero to *"Just the headlamp + spare batteries left."* for the final item. The line stays the same until you reach the next stage, so it doesn't change on every tick.
-- **Hidden activities** — Activities flagged as hidden in the admin panel are left off the selection page. They appear when someone clicks **Pack it!** ten times in quick succession (at most 0.5 s between clicks) while nothing is selected. The revealed activity is pre-selected, and its lists and short links work like any other. The sample data hides one: *Zombie apocalypse*.

 - **Shareable short URLs** — Each unique activity selection is stored under a deterministic 5-character hash, producing a permanent link short enough to share comfortably over chat or read out loud.
 - **Installable PWA** — A web app manifest, theme color, and maskable icons let PackIt be installed to the home screen on mobile or as a standalone app on desktop.
 - **Works offline** — A service worker (`sw.js`) caches the app shell and every list you have opened, which is what makes an installed PackIt useful at the trailhead. Pages are network-first, so an online visit always reflects the latest admin changes and falls back to the cached copy only when the network is gone. A list never opened on the device shows `offline.html` instead. The admin panel is deliberately never cached.
