Start the setup wizard blank and add a Run setup again button

The first-run seed no longer inserts the original vendor's name, address, contact
details, PAN or bank account; the wizard now starts empty and requires a name and
state. Settings > Data gets a Run setup again button that clears the onboarded flag.
Re-running the wizard keeps the active invoice series unless the prefix or padding
changes. The sample logo moves out of public/ so it no longer ships in the app.
