don't join spans on count traces query

[dinmukhamedm]

Important

Simplify count_traces query in trace.rs by removing span joins and adjust SessionsTable UI in sessions-table.tsx.

• Database Query:
  • Modify count_traces in trace.rs to avoid joining spans, simplifying the query.
  • Add add_date_range_to_query call in count_traces for date filtering.
• Frontend:
  • Set column sizes in SessionsTable in sessions-table.tsx.
  • Rename headers in SessionsTable for clarity (e.g., 'Token count' to 'Total tokens').
• Misc:
  • Add comment in spans.rs for LiteLLM auto-instrumentation handling.

  Confidence changes required: 0%
  The size property is added to multiple columns in the SessionsTable component. This is a new addition and seems consistent across all columns, so no issues here.
