Add year-scoped drink data, UserPayment model, German verbose names

Drink gets a year field (default 2024 for legacy rows), with name+year
unique together so each festival can have its own price/crate config
without overwriting the previous year. User balance properties
(consumed_drinks_price, paid_amount, open_balance) and the new
current_year() helper all filter by current year so year-over-year data
stays separated.

UserPayment model tracks per-user payments (cash/PayPal/bank/other)
against their drink tab, separate from Donation (event-level income).

Verbose names + Meta verbose_name(_plural) added across all models, and
LANGUAGE_CODE set to "de" so the admin renders German throughout.

Drink gains a few derived properties (crates_full_returned,
crates_remaining, bottles_consumed, bottles_remaining,
remaining_purchase_value) used by the upcoming admin and dashboard
views.
