fix: her evidence comes from the trace, not from a form field

Case 58325 died submitting findings: the submit_decision call arrived with
no `data` at all. The final model reply was exactly 4,096 output tokens —
the service's cap — so the JSON was cut off mid-call. Asking Ava to paste
16 full SQL statements into sql_log, on top of a summary, root cause, five
recommendations and a scanned-summary, is what pushed one tool call past
the limit and lost the whole investigation.

The platform already records every statement the agentic tool sends,
verbatim, with Databricks' own SUCCEEDED/FAILED and the row count. So
SqlEvidence now renders from the trace and treats sql_log as a one-line
index per step. Her charter gained hard per-field character limits to
match (sm2/custom-apps/denials-investigator/05_ai_employee.sql).
