[ENHANCEMENT] Option to detect and visualize repetitive text blocks.

When tracing agents, it's common to see prompts that combine a) variable text and b) static text defined in templates that are included in multiple prompts (for example, a system prompt).

It would be nice if Phoenix cuold identify repetitive text patterns (prompt templates) and visualize them in other color, inside a text container that can be labeled, expanded and collapsed.

Example

Let's say we traced this input prompt:

We can now click the text block and assign it a custom label:

This way we could add it a custom label and only see:
