Restore graph task and group coloring via Chakra palette tokens

Custom operator and TaskGroup colors disappeared in Airflow 3: the
ui_color/ui_fgcolor attributes were kept but the new UI ignored them, so
teams that relied on color to parse large graphs at a glance lost that
signal (see the demand on the linked issue).

Bring the coloring back in a way that fits the new opinionated theming:
the value must be a Chakra palette token (e.g. blue.500), which resolves
through a theme-controlled CSS variable and therefore stays legible in
both light and dark mode and under custom themes -- the dark-mode and
accessibility concerns that drove the original removal. The graph paints
the node fill from ui_color and the operator label from ui_fgcolor, as in
Airflow 2.x, while the border keeps showing run state. Legacy hex/named
values can no longer adapt to the theme, so they are ignored by the graph
and emit a warning for user-authored operators and task groups.
