style(header): hover moves the icon, never the button

A global `.btn-icon-header:hover { transform: rotate(45deg) }`, meant for
the settings gear, turned every header icon button on hover, so the folder,
Tiles, Split and the rest swung their rounded hover background into a
diamond. Three buttons had already cancelled it one by one (the font-size
buttons, notifications, the sidebar toggle).

The rule is gone, and with it those three overrides. Hover motion now moves
the icon only:
- the settings gear's icon turns 45 degrees (one tooth, so it lands on the
  same shape);
- the Tiles button's four squares spread apart, each toward its corner;
- the folder cross-fades to an open folder (a second drawing in its SVG,
  `.icon-folder-closed` / `.icon-folder-open`);
- every other icon just takes the hover colour.

Pointer devices only (`@media (hover: hover)`, so a tap cannot leave an icon
stuck mid-motion), and the transitions are off under reduced motion.

Owner request: the Tiles and folder buttons "weirdly turn" on hover.
Checked live on a dark and a light skin (rest, mid, end frames). Pinned by
test/header-icon-hover.test.ts, mutation-checked five ways (the button
rotation back, the open drawing missing, the motion not hover-gated, a
square spreading toward the wrong corner, reduced motion keeping its
transition). Gate: 507 files, 9798 tests passed.
