[NaitikVerma6776]

Summary

• Adds Vitest + Testing Library coverage for the GSoC web console (web/), which previously had no tests and no npm test in CI.
• Covers session/auth (expired tokens, vague 401 copy, dead-token reload), run/sample mapping (Linux+Windows grouped per commit, PR runs kept out of test history), href allowlists, caption cue parsing, Login, failing-run DiffDrawer, and status badges.

Test plan

• cd web && npm test (32 tests)
• cd web && npm run lint && npx tsc -b
• Confirm the Web console workflow runs npm test
