Directory narrow lists: small UX follow-ups

Seen during the 1024px visual check for Task 7229 (Directory › Projects and Machines › Nodes beside an open item). 1. Projects list, narrow: when a long name pushes the org chip off its line, the row gives no other cue to the org. Add the org to the row's hover title (e.g. "org-a-probe-projects · Operator") when the chip is not shown, or always. 2. Node detail pane at 1024px: the Overview grid's "Created" value wraps onto two lines ("Oct 18, 2026, 02:04 / PM") while the neighbouring cells have room. Keep the date on one line (shorter format or wider cell). 3. Machines sub-strip beside an open node (1024px) shows only "Nodes Hosts >": Pools, Connections, NodeLink and Brains sit behind a chevron. Consider the overflowMenu ("More ▾") mode used by the project pane so every section stays one click away. Out of scope: the Tabs chevron fix and the Projects name/org layout (Task 7229). Done means: - Each item is fixed and covered by a web test, or declined with a reason, and checked visually at 1024px.

Merged #5917: Projects rows show the org on hover; node Overview Created/Last Seen fit one line (short stamp, full on hover). Machines More was already on develop (Task 7193). Quick gate + tests green; 1024px visual check done. Draft follow-up 7251.
