fix(ui): tooltip wrap bound comes from the popup text child's authored P0x3D, and tooltip text left-aligns

Owner screenshots vs retail at the CA5 re-check caught both:

Wrap width: the popup skins' shared TEXT CHILD (0x10000396) authors
P0x3D=256 on all four skins — live-DAT probed, now pinned by an
installed-DAT test. Retail's InqSizewMargins UITS_MAX_WIDTH reads the
text element's 0x3D BEFORE the display-width fallback, so retail wraps
tooltip text at 256px; our measure pass used the display width because
TS-85's 'zero elements author P0x3D' sweep had only covered hover
TARGETS, never the popup skins. ApplyTooltipText now measures and
re-wraps at the text child's authored bound, falling back to the display
width only when none is authored.

Alignment: tooltip text rendered centered where retail hugs the left
edge. The skin authors no justification; retail's unauthored default is
Left, our importer's ElementInfo default is Center — the same
wrong-default class as #410's VJustify finding, now recorded there as the
horizontal sibling. Point-fixed in the presenter exactly as the chat
transcript already does; the client-wide default flip stays #410's scope.

The two-pass sizing test now models the real skin (max width on the text
child) and asserts left alignment. Full hermetic suite 15,332 passed / 0
failed; the new live-DAT pin passes against the installed DATs.
