fix: constrain request path table cells

[nanookclaw]

Summary

Fixes the requests index layout so unusually long request paths cannot widen the table and push Status/Duration out of view.

The path column now renders through a dedicated request-path-value span with the full path preserved in the title, while the requests table uses fixed layout and stable widths for the metadata columns. This keeps the right-side columns visible and still lets users inspect the complete path on hover.

Verification

• git diff --check
• dotnet test DebugProbe.AspNetCore.Tests/DebugProbe.AspNetCore.Tests.csproj (blocked locally: dotnet is not installed in this environment)

Closes #94

[georgidhristov]

Tested locally and the fix works as expected.

Long request paths no longer break the requests table layout, and the status/duration columns remain visible. The full path is still accessible via hover/title, so this resolves #94 cleanly.

Approved.
