theme: stop inheriting Textual's neon orange; ship our own palette

Nobody picked that orange — it's #ffa62b from Textual's default textual-dark,
which sets accent AND warning to the same value, so every border, title bar and
the quit dialog were all the same neon. Meanwhile the code views already use a
coherent muted palette (amber #b58900 for matches and the spinner, #6a9955 green
for comments, #264f78 blue for the word highlight), so the chrome was the only
thing shouting.

Register an "idatui" theme in the same family: desaturated blue-greys for
background/surface/panel, amber (#b58900 — the exact match highlight colour) as
the accent, a burnt orange (#c9762f) for warning so it reads as care rather than
as another accent, blue (#5aa0d6) reserved for focus, and the reds/greens we
already used for failure and comments.

Title bars were color:$text on the accent, which was passable on bright orange
and muddy on amber; they're now dark-on-amber and bold, which reads as
intentional.

Suite 192/0, project UI 23/23.
