Project › Memory tab and project header: polish

Seen on a local stack while verifying Task 6711 (project page in the Directory side pane, 420–1920px). 1. The Memory feed row shows a "Code map: Active" chip next to the caption "Code map: not built yet". Merge them, e.g. by putting the code map sha (or "not built") in the Code map chip itself. 2. The project header puts "Org Operator" beside the title on a lower baseline than the breadcrumb, so it looks out of place. Align it with the title or move it onto the breadcrumb line. 3. In the side pane at ≤780px the project tab strip wraps "Memory / MicroVM / Advanced" onto a second row. Give the overflow tabs a "More" menu, or use the scrolling strip the task pane already has. 4. Feed chips wrap onto two rows in the side pane even when most are Active. Put the Active feeds behind one "4 active" chip and show only the stopped ones in full. Out of scope: memory voting, trust or demotion logic; any API change. Done means: - Each item above is fixed, or the reason it was dropped is in the PR body. - Screenshots of the Memory tab at 420px and 1280px are in the report.

Fixed all 4 items: Code map chip carries its sha, running feeds fold into one "N active" chip, header aside sits on the title row, project tabs overflow into a More menu instead of wrapping. Quick gate green, visual check done at 420–1920px. PR #5677 merged; its deploy was superseded by a newer develop push. Follow-ups filed as draft 6799.
