[feat] Improve trigger delivery inspection

[ashrafchowdury]

Context

Trigger delivery results were difficult to inspect in the Agent Playground. The table sat against the drawer edges, long results were truncated, and trace-bearing deliveries had no direct path to the Trace drawer.

Changes

The deliveries drawer now adds surrounding spacing, expands the Result column from 280px to 380px, and wraps error and result text instead of truncating it.

Trace-bearing rows now include a View trace action. It opens the matching trace and span while keeping the Deliveries drawer open underneath, so closing the trace returns users to the same delivery list.

The trace action uses an optional host callback, which keeps @agenta/entity-ui independent from OSS trace drawer state.

Before:

• Results were ellipsized in a narrow column.
• Diagnosing a delivery required navigating to its trace separately.

After:

• Full results wrap within the table.
• View trace opens the associated trace directly from the row menu.

What to QA

• Open an agent trigger's Deliveries drawer. Confirm the table has top and side spacing and long errors or results wrap without being truncated.
• Open the row menu for a delivery with a trace. View trace should open the correct trace and selected span.
• Close the Trace drawer. The Deliveries drawer should remain open on the same list.
• Open a delivery without a trace. View trace should not appear.
• Regression: confirm Run in playground, View payload, and Copy event ID still work in both light and dark themes.
