feat: add quick payment action and improve copy button UX

Mini App Home Screen:
- Add 'Record Payment' button to utilities and rent period cards
- Pre-fill payment amount with member's share (rentShare/utilityShare)
- Modal dialog with amount input and currency display
- Toast notifications for copy and payment success/failure feedback

Copy Button Improvements:
- Increase spacing between icon and text (4px → 8px)
- Add hover background and padding for better touch target
- Green background highlight when copied (in addition to icon color change)
- Toast notification appears when copying any value

Backend:
- Add /api/miniapp/payments/add endpoint for quick payments
- Payment notifications sent to 'reminders' topic in Telegram
- Include member name, payment type, amount, and period in notification

Files:
- New: apps/miniapp/src/components/ui/toast.tsx
- Modified: apps/miniapp/src/routes/home.tsx, apps/miniapp/src/index.css,
  apps/miniapp/src/theme.css, apps/miniapp/src/i18n.ts,
  apps/bot/src/miniapp-billing.ts, apps/bot/src/server.ts

Quality Gates: ✅ format, lint, typecheck, build, test
