Targeted round over 3cd0c525's fix surfaces: 14 raised, 14 fixed.
- VideoEditor: the "only X of Y clips" toast went silent exactly on the job-cap/quota refusal it was
written for (req had already reported the error); it now always shows. The cut list holds still while
Create queues, and a retry continues the "(i/N)" series.
- ChannelPage: Subscribe/Unsubscribe use Button `loading`, "Load more" and ChannelDiscovery's Subscribe
block the click with aria-disabled instead of native disabled; busy Block/Hide no longer light up on
hover.
- listNav: an item can name itself (`navItemAttrs(i, name)`) — Plex posters, seasons, episodes, message
rows and download rows pass their title; focus on a toast's Undo keeps the removed card's slot.
- AnchoredPopover: the hand-back only for focus-managed surfaces (a hover card no longer pulls focus
back); the dead panel-ref check is gone.
- AccountPanel: no confirmation mail offered to the demo account; send_failed copy no longer blames
the message for an unreachable server. Pager comment points at scrollParent.
