S3 lifecycle docs: recipes page, accurate metrics, drop stale knobs
- add S3-Lifecycle-Recipes with copy-paste configs and verification
- link the Architecture/Monitoring/Operator/Troubleshooting/Recipes
sub-pages from the sidebar; they were orphaned from nav
- fix Prometheus metric names to the real SeaweedFS_ namespace; the
bare s3_lifecycle_ names matched nothing in a scrape
- main page: raw XML wire format, 1 MiB / error-code validation table,
Transition rejected (not ignored), GET legacy directory-TTL fallback
- document events_total and schedule_depth; run-shard flag table
- drop max_runtime_minutes (removed); per-pass cap is now the
scheduler Execution Timeout, default effectively unbounded
- Days < 1 is client-side only; server stores Days=0 as a no-op
