fix(chargen): Campaign CC gate round 1 Batch B — authored selection states, label state, zoom/swatch feedback

GF-1/GF-8: UiButton now recognizes retail's custom Unselected/Selected
radio-pair (0x10000016/0x10000017), bypassing the standard Normal/
Highlight machine that never admitted those state names — .Selected now
lights the heritage/template/gender/Face-Clothes rows it was always a
no-op for.

AP-222/GF-11b: per-state label color/outline (dat 0x1B/0x21) now applies
off the REQUESTED retail state id, not the art-gated committed
ActiveState — resolves the Appearance spins' current-part highlight
(text recolors even though no Highlight art exists on either client) and
the Town caption's Normal-to-white swap.

GF-11c: UiButton.LabelBox lets a lifted caption with its own authored
rect draw there instead of the face-relative offset that's only correct
when the label is authored directly on the button (heritage/template
family, unchanged).

GF-9: wires the real nine companion overlay elements (SetColor's
SetVisible mechanism) that swatch clicks were always meant to drive,
retiring AP-215 item 1 (the swatch.Selected substitution was a permanent
no-op — swatches author no Highlight media at all).

GF-10: zoom buttons now set the retail-mirrored mutual-exclusive
Highlight/Normal pair on click; InitializePage carries no initial
SetState for either button, so both stay at "Normal" until first click.

Register: AP-222 retired (mechanism identified and ported), AP-215
narrowed (item 1 retired, item 2 unrelated and unchanged), row count
recount corrected 164 (was already one high before this batch).

App suite 5282/3 (was 5266/3), Runtime 1735/0 unchanged. Fixture + live-
DAT tests only — no graphical client launch.
