Recovery scripts do not call `recover_state_if_missing`

[dmeiser]

Synthesized from full-repo review (KW-REVIEW-SYNTHESIS).

• Severity: Medium
• Location: scripts/recover-deploy.sh; scripts/recover-destroy.sh
• Summary: The recovery scripts source ephemeral-recover-common.sh and call init_backend / import_ephemeral_resources, but never attempt the S3-version restore that ephemeral-env.sh down does. The two "state missing" paths behave inconsistently.
• Recommendation: Call recover_state_if_missing in recover-destroy.sh before falling back to import.
• Source reviews: glm-review (PR fix(ci): make ephemeral per-PR test environment teardown reliable with manual cleanup and recovery workflows #118)
