ChuckBuildsandClaude Opus 5 2f42d179f6 fix(composer): point the align toolbar at the anchor-clearing path ...

Two alignment implementations existed and the toolbar used the wrong one.

alignElement(dir) set el.x/el.y and stopped there. resolveAnchor turns
anchor='right' into `dim - val`, so with xAnchor='right' an "align left"
(el.x = 0) resolved to x = MATRIX_W and the element jumped to the far right
edge -- the opposite of what was asked. It also never touched el.x0/el.y0, so
a line's endpoints were left where they were.

_alignElement already did both correctly: it clears the anchor so the stored
value is absolute, and moves x0/y0 for lines. Its six wrappers -- alignLeft,
alignHCenter, alignRight, alignTop, alignVCenter, alignBottom -- existed and
had no callers at all.

All six toolbar buttons now call the wrappers, and the legacy method is
removed rather than left to drift back into use.

Tests: the toolbar calls each wrapper and no longer calls alignElement, the
legacy definition is gone, and _alignElement still clears the anchor and moves
line endpoints. Two of them fail against the previous markup.

Full suite 4062 passed, the one failure being test_install_lowmem
(pre-existing, awaiting #492).
