feat(phai): Improve SQL table readability in AI Chat

Feature request

Is your feature request related to a problem?

Yes. SQL tables rendered in AI Chat are constrained by a relatively narrow max-width container, which makes it difficult to inspect wide result sets or tables with many columns. Users cannot effectively use the available screen space within the AI panel.

This creates friction when reviewing query results and can force users into workarounds, such as creating a new Insight solely to view the table in a larger layout, then deleting it afterward.

Describe the solution you'd like

Add an optional expanded viewing mode for SQL tables shown in AI Chat so users can inspect results in a larger, more usable layout without leaving the conversation.

Potential implementations could include:

• Expand button that opens the table in a larger modal or drawer
• Full-panel focused table view
• Resizable table container
• Better horizontal scrolling experience for wide tables

The goal is to improve readability and usability while keeping the default chat experience unchanged.

Describe alternatives you've considered

• Making all SQL tables full width by default. May negatively impact chat readability and consistency.

Additional context

Feedback:

“Really missing the ability to expand the sql tables in the AI chat to fill the full width of the AI panel. Right now it’s quite narrow (a hardcoded max width), and I can only use my available screen estate by creating a new insights that I then have to delete.”

No files, tests, or entry points are named. Start by locating the AI Chat component responsible for rendering SQL tables and review its existing layout and test coverage. Done means an optional expanded viewing mode improves readability while leaving the default chat experience unchanged.
