Problem

The generated Time consuming prepare and Time consuming bind example details show the wrong database, user, remote host and application. A synthetic log with db=demo_db,user=demo_user,app=demo_app,client=example.test instead displays database postgres, user demo_db, remote demo_user, application example.test, and a spurious query ID demo_app.

Both store_queries callers pass the aggregate report database followed by the actual database name to set_top_prepare_bind_sample, but its parameter list omits the actual database name. Every subsequent argument is shifted.

Change

Accept that existing argument and store it as the sample's database name, preserving the aggregate report key and all other caller contracts. Three production lines change; a self-contained CLI-to-HTML regression checks both prepare and bind examples.

Validation

• Base fb5e1bfe80e50180e77795bac49653cc92c6813d: 10 of 11 new assertions fail; fixed version passes 11/11 on Perl 5.38.2.
• Perl syntax, POD syntax and whitespace checks pass.
• Inputs are self-authored log strings; no database connection or production logs.
• Full upstream suite/Perl matrix not run locally (fixed /tmp outputs and upstream log fixtures outside this isolated check; optional JSON::XS absent). This PR is independent of Fix multiline prepare query continuation #888.
