The profile row only showed the description, so there was no way to tell
which profile a display actually has applied (whitepoint, curve type, file
provenance) without leaving the settings page.
- `ICCStatus` carries the descriptive metadata: class, tone-curve kind (plus
gamma or table size), vcgt channels/entries, white point chromaticity with
a derived CCT and standard illuminant name, file size and mtime.
- `internal/icc` gains `WhitePointXY`, `WhitePointCCT` (McCamy),
`WhitePointName` (D50/D65) and `TRCKind`, all covered by tests.
- Display Config's Color Profile row gets an info button that opens
`ICCProfileInfoModal` with those fields and the profile path, alongside
the existing browse/remove actions.
- `dms icc info` reports the white point as name/xy/CCT instead of raw XYZ.
