Add staff dashboard, payment flow, seed extra 2026 expenses

Self-service /suff/pay/ page lets users record their own payments
(cash/PayPal/bank/other) against their tab. Open balance is shown on
/suff/me/ alongside total and paid amount, with a Bezahlen button when
something is owed.

Staff-only /suff/dashboard/ replaces the drink_stats / total_balance /
user_stats CLI commands with a mobile-friendly festival view: overall
refinancing progress bar (Spenden vs. Ausgaben with Bilanz), drinks
refinancing bar (sales revenue vs. purchase cost with profit), per-drink
sold/total/balance, open balances per user, and fun facts (top
spender, top drink, busiest day, and top user per festival day).
Linked from /suff/me/ when the logged-in user is staff.

seed_drinks_2026 also creates the non-drink Payments we already know
about (toilets, drinks/equipment down payment, band fees per stage day),
idempotently keyed on (purpose, date).
