Sent tab subject column disappears in detail

On Settings › Email › a Gmail connection › Sent, opening a linked run or task in the list/detail pane narrows the list. The subject column then disappears entirely, and only the disc, recipients and status remain, so you can't tell which send you opened. Found during Task 9458's visual check at 1280px. - Keep the subject readable in the narrowed pane, for example with `titleWrapAt` or by gating the To/status slots on the pane's width rather than the window's. - Drop the redundant status chip first; the row's disc already shows Sent or Failed. Out of scope: changing what the Sent list shows at full width. Done means: with a run open beside the Sent list at 1280px, every row's subject is visible. Show this in a screenshot.

Sent list is now its own query container: beside an open task/run (388px list at 1280) the status chip drops, then the source; To narrows and the subject wraps. Visual check done, every subject readable. Quick gate green; PR #6782 queued to the lane.
