FE-427: Handle inheritance in type graph viz, fix table empty state

[CiaranMn]

🌟 What is the purpose of this PR?

A few small fixes:

1. The type graph viz wasn't handling inheritance (inherited links not showing), nor displaying icons on nodes.
2. The entities and type tables weren't showing the 'No results shown' text.
3. Commented out the user cover image editing UI as the cover image isn't actually shown
4. Fixed some tooltips in the type editor that could clash with each other.

PR Summary

Low Risk
Frontend-only UX and visualization logic; no auth, data persistence, or API contract changes.

Overview
Fixes empty filtered tables in the shared Grid by treating zero rows as an empty state (not real data): getCellContent and rows now require sortedAndFilteredRows.length > 0, and the idle message is "No results with the applied filters." The types table uses displayedRowCount so height still reserves one row for that message.

The type graph visualizer walks entity type allOf ancestors, merges inherited links (deduped by link base URL), resolves link schemas from full entityTypes context, and sets node icons from the nearest ancestor that defines one.

User profile edit modal: cover image add/change/remove controls are commented out (cover not shown on profile yet); hidden upload handlers remain.

Type editor inherited link rows use a single title tooltip for the inheritance source and drop redundant read-only tooltips on destination and cardinality cells to avoid overlapping popovers.

Pull request overview

This PR applies a set of frontend UX fixes across the type editor and type/entity tables, focused on improving type graph visualization fidelity (inheritance + icons) and restoring meaningful empty states.

Changes:

• Extend the type graph visualizer to include inherited links and inherited icons when building graph nodes/edges.
• Ensure table/grid components render a visible empty state (minimum 1 row) so “no results” messaging appears.
• Temporarily disable cover image editing controls in the user profile modal header and adjust tooltip behavior in the type editor.
