[bug-hunter] Fix saved-before-quit recovery classification

[r3dbars]

Summary

• fixes .savedBeforeQuit meeting failures so retained audio is classified as recoverable instead of permanent when the failed row is not marked directly retryable
• adds a regression test for the finish-later path from Home

Signal

Recent PR #815 added active-meeting quit safety and a savedBeforeQuit failure kind. Review feedback on that PR flagged that MeetingFailureExplanation added the kind to save-stage reporting, but not to the sibling retryability/outcome switches.

Root Cause

MeetingFailureExplanation listed save-stage recovery kinds in multiple switches, and .savedBeforeQuit was missing from resolvedRetryability and resolvedOutcomeKind.

Verification

• bash build-deps.sh --force (needed because local deps were stale)
• bash build.sh
• TRANSCRIPTED_DISABLE_FILE_LOGGER=1 bash run-tests.sh
• bash run-integration-smoke.sh

verdict: no-findings-but-human

findings: none from this pass.
actions: human signoff recommended because this is a draft meeting-recovery behavior fix, even though the classifier/test change looks focused.
