improvement(tables): show a tooltip on truncated column headers

[TheodoreSpeaks]

Summary

• Column headers in the table grid now reveal their full name in an emcn floating tooltip when the text is clipped — gated on isTextClipped, so an untruncated header never shows one
• Covers both surfaces: the standalone table page and the embedded table view in the mothership chat page (same TableGrid), plus the workflow/enrichment group header
• New HeaderLabel component replaces the three hand-rolled truncating spans

Type of Change

PR Summary

Low Risk
Presentation-only change in table grid headers with no API, auth, or data logic touched.

Overview
Truncated table column headers and workflow/enrichment group names now show the full label in a floating tooltip on hover, using a new shared HeaderLabel component.

HeaderLabel truncates with an ellipsis and only opens the tooltip when isTextClipped says the text is actually clipped, matching the pattern used elsewhere in the app.

It replaces the previous truncating <span>s in column-header-menu (read-only and interactive column headers) and workflow-group-meta-cell (group header name).

Greptile Summary

The PR introduces a reusable clipped-header label that displays the full text in a floating tooltip and applies it to column and workflow-group headers.

• Adds HeaderLabel using the shared floating-tooltip utilities and clipping predicate.
• Replaces three hand-written truncating spans across the table-grid headers.
• Updates both consumers to use absolute alias imports.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
