ayushsolanki29/soseki-app ? reverse-engineered prompt

Build me a self hosted business workspace for freelancers and small agencies called Soseki.

I want one clean app where I can manage clients, projects, invoices, payments, expenses, questionnaires, and support tickets without juggling spreadsheets or a bunch of tools. The dashboard should show a quick overview of the business, with charts, totals, and useful stats. Clients should have detailed profiles, projects should link to invoices and expenses, and invoices should support multiple currencies with PDF downloads and payment tracking. Expenses should also support multiple currencies and attach to clients or projects.

Please include a client portal so customers can log in, see what they owe, and pay online. I also want public questionnaires that can be shared without login, plus a simple support ticket area with threaded replies. Make the setup feel polished and easy to use, with a modern clean interface. If you need to look up current docs online, go ahead.
