fix(edit): curate the CalDAV colour picker in painted space (#22)

The picker paints every swatch through pastelize, which pins lightness to
a constant and caps saturation — so the raw palette's lightness axis is
invisible on screen. Curating in raw space (as the first pass did) left
near-identical painted swatches (navy/blue/midnightblue all paint as one
mid blue) and stranded every neutral as an identical pale tint in a run of
"pinks" at the end of the grid.

Move dedup, thinning, and ordering into the painted (pastelised) space the
user actually sees: colours that paint identically collapse to one,
oversized palettes drop washed-out neutral-origin tints (painted chroma
below a floor) and thin by CIE76 ΔE in painted Lab, and the survivors sort
continuously by painted hue with the wheel cut at its widest gap. The CSS3
147-colour dump now lands at ~33 distinct, rainbow-ordered swatches with no
neutrals stranded at the end.

The hue/saturation shaping moves into a shared domain pastelArgb() so the
picker paints exactly what curation reasons about; ui/pastelize wraps it and
only picks the theme's brightness.

 ### Fixed
+- A tidy colour picker on CalDAV calendars. For calendars synced by a CalDAV
+  app (such as DAVx5), the event colour picker showed every colour the account
+  publishes — nearly 150 swatches in alphabetical order, many of them
+  duplicates or near-identical shades. The picker now shows only visually
+  distinct colours, arranged as a rainbow; near-duplicate shades and the
+  washed-out neutrals are folded away so no two swatches look alike. Picked
+  colours still sync exactly as before, and calendars with hand-picked
+  palettes (like Google's) are unaffected. Thanks to @ptab for the report
+  ([#22]).

+ * named colours — including exact-value aliases (aqua/cyan, the gray/grey
+ * spelling pairs) and dozens of visually indistinguishable whites and grays
+ * (#22).
+ *
+ * Crucially, curation runs against the colour the picker actually *paints*, not

+ * it pins lightness to a constant and caps saturation, so the raw palette's
+ * lightness axis is invisible on screen. Two raw colours that look different —

+ * space, as before, left near-identical painted swatches and stranded the
+ * neutrals as a run of look-alike "pinks" at the end of the grid.
+ *
+ * Three steps, all in painted space:
+ *  1. Collapse swatches that paint identically to one (alphabetically-first key
+ *     wins, deterministically) — this folds aliases, dark/light shades of a
+ *     hue, and all the neutrals together.
+ *  2. Oversized palettes (> [CURATION_TRIGGER_SIZE]) drop the washed-out
+ *     neutral-origin tints (painted chroma < [PASTEL_CHROMA_FLOOR]) and are
+ *     then thinned to visually distinct colours: most vivid first, a colour is
+ *     kept only when at least [MIN_DELTA_E] (CIE76, painted Lab) from every
+ *     colour already kept. Small palettes are already curated by their adapter
+ *     and pass through whole.
+ *  3. The survivors are ordered like a rainbow — continuously by painted hue —
+ *     with the wheel cut at its single widest empty gap so the one unavoidable
+ *     seam lands in dead space and no hue family is torn across both ends.
