Fix final indentation error on line 161 - remove leading spaces from audit_history_sample

This is the final indentation fix. Line 161 had audit_history_sample indented inside the with gr.Blocks() block. Removed all leading spaces so the variable is declared at module level. All 4 sample data variables (consent_events_sample, branches_sample, diagnostics_sample, audit_history_sample) are now correctly indented at column 0. The app should now start without any IndentationErrors.
