ref(seer): Propagate viewer_context to background tasks and utilities

[azulus]

Pass SeerViewerContext to Seer API wrapper call sites in background tasks and utility modules.

PR #109697 added an optional viewer_context parameter to all Seer API wrapper functions. This PR updates:

• context_engine_index.py: Pass organization_id from org_id param
• seer_explorer_index.py: Pass organization_id from project tuples
• trace_summary.py: Pass organization_id + optional user_id (when user is not None/anonymous)
• supergroups.py: Pass organization_id from param
• Skipped: seer_models.py (no auth), uptime/seer_assertions.py (no context)

No behavior change — viewer_context defaults to None which preserves existing behavior.
