fix: collapsed strip, workspace-mode search, image dialog chat list

- Collapsed menu: its own plain white 52px column against the tiled ground,
  no border line, in both views. Flat, it had no edge.
- Collapsed + workspace launcher: assistant.css set the rail track to 0 and
  beat the 52px rule, so the collapsed menu (name card included) vanished.
- Search follows the view, not the URL: the workspace launcher keeps
  /assistant, so Workspace searched chats.
- Create image, "Base it on": a native <select> list is as wide as its
  longest option, so full titles pushed it past the dialog. Labels now keep
  the whole words that fit the select's width; the full title is on hover.

Verified in Chromium: account menu items on top in all 8 states; collapsed
strip 52px white with the name card at the same place in all 3 views;
search placeholder and results per mode; dropdown widest label 500px in a
506px box (279 in 280 on a phone).
