fix: bump debug share paste TTL from 1 hour to 6 hours (#11240)

Users (Teknium) report missing debug reports before the 1-hour auto-delete
fires. 6 hours gives enough window for async bug-report triage without
leaving sensitive log data on public paste services indefinitely.

Applies to both the CLI (hermes debug share) and gateway (/debug) paths.
