Pull request overview

This PR adds UI support for filtering traces by span status (OK, ERROR, UNSET), building on backend support added in PR #20540. The PR also refactors URL generation utilities for assessment chart tooltips to improve maintainability.

Changes:

  • Added span status filter support to the traces table UI with EQUALS and NOT_EQUALS operators
  • Refactored URL generation functions for assessment charts to support flexible filter composition
  • Enhanced assessment chart tooltips to link to traces filtered by time range and assessment existence
  • Fixed backend span filter logic to ensure multiple conditions apply to the same span
