fix: revert jQuery to 3.7.1 and harden export resilience

Revert jQuery 4.0.0 to 3.7.1 for Bootstrap 4.6.2 compatibility.
Add unsigned right shift to export test score calculation to match
production logic. Wrap Gmail getLabels() in try-catch so label fetch
failures degrade gracefully during exports. Reconcile missing Outlook
batch responses so silently dropped requests produce explicit errors.
