Important

Fixes to ensure 'to' date is respected in date range filters across multiple components, with column identifier renames for consistency.

• Behavior:
  • Ensure 'to' date is respected in date range filters in observations.tsx, scores.tsx, sessions.tsx, and traces.tsx.
  • Adds conditional filter for 'to' date in dateRangeFilter if dateRange.to is defined.
• Misc:
  • Renames column identifiers to lowercase (Start Time to startTime, Timestamp to timestamp) in observations.tsx and traces.tsx for consistency.
