fix(customize): remove uglifycss to preserve CSS Color Level 4 syntax

uglifycss v0.0.29 (unmaintained since 2019) corrupts space-separated
rgb() without alpha channel — valid CSS Color Level 4 syntax — by
converting it to an invalid truncated hex value (e.g. rgb(0 0 255) → #00).

Remove minification entirely. Custom CSS is typically small, so the
minification benefit is negligible compared to the risk of breaking
valid modern CSS syntax.

Fixes #11274
