Fix demo reset: wipe bills/expenses, fix apostrophe display bug

- Add Bills and Expenses flags to RemoveSeedDataOptions
- RemoveSeedDataAsync: delete BillPayments + BillLineItems + Bills, then
  Expenses for the company when those flags are set
- ResetDemoCompany action: enable Bills=true and Expenses=true so all
  seeded AP data is cleared before re-seeding (was skipping on second reset)
- Fix apostrophe in success message (was ' in C# string, double-encoded
  by Razor to literal ' on screen)
