feat: remove end time column from traces table

[Brilly-Bohyun]

Purpose

The traces table shows start time, end time, and duration, making rows
cluttered. Start time and duration provide sufficient timing information.

Resolves openchoreo/openchoreo#4704

Goals

Remove the redundant End Time column and make trace names easier to read.

Approach

• Remove the End Time header, row cell, and column sizing entry.
• Increase the Trace Name column width from 12% to 32%.
• Preserve end-time data and the span detail view.
• Add a patch changeset for the observability plugin.

Verified in the Portal's Catalog → Traces page using two mock traces. The temporary mock setup is not included in this PR.

User stories

Users can read longer trace names without redundant timestamps cluttering the traces table.

Release note

Removed the End Time column from the traces table and widened the Trace Name column.
