[Icons] Author icon emphasis colors as palette roles (#7789)
* [Icons] Author icon emphasis colors as palette roles

The emphasis levels were computed from the accent at paint time, so a
theme could not vary them: every theme got the same derived strong and
soft tones, and a semantic hue was pushed toward the accent whether the
author wanted that or not.

Give each family three authored roles instead. Icon/IconStrong/IconSoft
carry the neutral glyph ink and Positive/Negative gain the same Strong
and Soft companions. Emphasis becomes a lookup inside the family, and a
caller that names a variant pins that level at every emphasis. The paint
path returns the authored color verbatim; only the filled treatments keep
their saturation floor, because carrying a disc or a fill is a treatment
decision.

Shipped palettes author the full ladder for both schemes; the palette
editor exposes the new rows and the generator writes them. System keeps
deriving its neutral ink from the platform palette, since it ships no
palette of its own.

* [Icons] Keep the authored emphasis in filled treatments

The saturation floor was added while the emphasis levels were still
computed: it rescued the pale dark-scheme tones once a whole shape
carried them. With the levels authored, the floor overrides the author
instead: a quiet level jumped to the secondary saturation as soon as a
sticker or a badge painted it, so the ladder only existed for line
glyphs.

The authored tone is now the top of the fill gradient and the treatment
only darkens the bottom for depth, so every treatment renders exactly the
level the palette stores. The badge glyph ink no longer guesses the
scheme from the tone's value: an authored quiet level is a dark color on
the dark scheme too, so the scheme is passed in from the surface palette.
The preview sheet renders every shipped palette theme, three glyphs per
family, and each row prints the authored tone and the darker bottom.

* [Icons] Order the emphasis ladder by chroma, not contrast

Contrast cannot order the ladder. On a dark surface the highest-contrast
tone is the palest one, so a 7:1 primary came out near-white while the
secondary kept the family's color; the ladder read inverted, and for the
shipped semantic greens and reds the primary level was already satisfied
by the secondary, so the two levels resolved to the same hex.

Emphasis is chromatic intensity now. Quiet recedes toward the surface at
the 3:1 non-text floor, secondary keeps the family color at the 4.5:1
text floor, and primary is the most chromatic tone the same floor allows.
Every level stays legible on the window and the button surface, and the
primary is a strictly more saturated member of its family on both
schemes. The reformatted palettes move the two upper levels onto the
shared floor and leave the quiet level alone.

* [Icons] Make the emphasis ladder structural on every theme

The chroma ladder landed with four P1s from review: reachContrast picked
its pole by background lightness instead of by what each pole can reach,
the generated neutral ink was solved on the window surface only, Fusion's
neutral family was still the green accent, and quiet sat below the text
floor while disabled reused the palette gray.

Pick the pole by achievable contrast, solve fallback and preview inks on
the harder of the window and button surfaces, re-author Fusion's neutral
trio in slate blue, and keep quiet on the shared text floor by muting its
saturation to 45% instead of blending it into the surface. Disabled is now
derived from the quiet ink, so it is structurally dimmer than every
enabled level on every theme.

Re-author all soft roles at a 4.60 target with a rounding margin, rebuild
the per-theme preview generator the rebase dropped, and add a Disabled row
to every treatment sheet.

* [Icons] Render preview glyphs at the sheet's device pixel ratio

The preview sheets paint on a 2x painter but rasterized each glyph at its
logical size, so every icon was upscaled on the way into the file and the
sheets read as blurry. Render each glyph at device size and tag the pixmap
with the ratio, so one source pixel lands on one file pixel.

* [Icons] Keep the System semantic ladder on the text floor

System authors no palette of its own, so its semantic family is fixed data
measured against whatever surfaces the platform provides. The ladder that
landed with the authored roles reused the old contrast-ordered values:
PositiveSoft and NegativeSoft sat at 2.76–3.90:1 on common light and dark
platform surfaces, and the strong level was less saturated than the
secondary, which is the inversion the chroma rule removes.

Re-author the six default semantic colors per scheme at the same 4.60
target the shipped themes use, against representative platform surfaces,
and mirror them in System's palette files. The new
DefaultSemanticFamilyMeetsTheLadderOnPlatformSurfaces test holds the floor
and the saturation order there, and shippedPalette's early return now says
why System is outside the authored-palette assertions.

* [Icons] Apply the CI clang-format output to the new tests

* [Icons] Adapt the treatment preview to the authored roles

The preview file is inherited from the treatment PR. Here the palette already
authors the fill tone and the badge takes an explicit scheme, so the generator
stops re-saturating the role and passes the scheme the sheet renders.

* [Icons] Author neutral System icon ink

The System theme derived icon ink from the platform palette, which rendered blue under the default palette. Author Icon/IconStrong/IconSoft explicitly: a black ladder in light mode, a white ladder in dark mode. Pin authorship, achromaticity and ordering in the render test.

# The System theme derives all of its colors from the platform palette
# (e.g. qt6ct's custom color scheme on Linux), so it must NOT ship palette
# overrides. Only the identity and semantic app colors are provided here, so
# buttons keep their classic greens while the actual palette stays native to
# the OS.
# The neutral icon family is deliberately not authored: the palette file is
# picked from the theme's scheme, which on Qt < 6.5 is always light and on newer
# Qt can be unknown, so a fixed black-or-white ladder would be invisible on a
# platform palette of the other scheme. Neutral ink derives from the live
# WindowText instead.
