Recent Search Duration

Motivation

Recent BLAST searches already show each run result, but the list did not expose how long the search took.

User-facing change

The Recent searches table now shows a secondary runtime line in the Time column. Completed and failed searches show Duration, while active searches show live Elapsed time.

API and IaC diff summary

No API or IaC changes. The frontend derives the value from the existing created_at and updated_at job timestamps.

Validation evidence

• cd web && npm run build
• Browser smoke on http://localhost:8090/blast/jobs confirmed rows render Duration labels without layout overlap.
