Populate paymentParams with actual data from database

- Updated ViewLocationCard to accept userSettings prop
- Replaced all hardcoded payment values with dynamic data:
  * Amount calculated from monthly expenses
  * Payer info from tenant fields (name, street, town)
  * Recipient info from userSettings (name, street, town, IBAN)
  * Reference number and description generated from location data
- Created getUserSettingsByUserId function for fetching owner settings on public pages
- Updated LocationViewPage to fetch and pass userSettings to ViewLocationCard
