feat(seaweedfs): add timeout and buffering annotations to tenant ingress

Align tenant SeaweedFS S3 ingress annotations with system configuration
by adding proxy buffering, request buffering, and timeout settings.
This ensures consistent handling of large file uploads and prevents
connection timeout issues for tenant buckets.

Changes:
- Add proxy-buffering and proxy-request-buffering annotations
- Add proxy-read-timeout, proxy-send-timeout timeouts (3600s)
- Add client-body-timeout and client-header-timeout settings
- Add service-upstream annotation for load balancing
