feat: automate deposit flow + fix listUsers pagination

- Rewrite DepositWithdrawModal to send TX automatically via assetHubApi
  instead of manual copy-paste-hash flow
- Fix listUsers pagination bug (default 50) in 4 edge functions by
  adding perPage: 1000 - fixes P2P offers not showing for users
- Add new i18n keys for automated deposit states in all 6 languages
