Unify colour scheme and CSS as one Style list in settings UI (ticket 047)

The settings panel had two separate sections — "Colour scheme" (built-in
palettes) and "CSS" (imported/linked stylesheets) — even though the data
model (tickets 012/020) already treats both as equally-selectable themes
via custom_theme_id. Merge them into one "Style" section presenting a
single list: built-in scheme pills plus imported/linked entries, any of
which can be a palette swap or a full layout override, with copy that no
longer implies "colour scheme" and "CSS" are separate features.

Traced and manually verified (via a running dev server) that a
user-supplied stylesheet is not constrained to --c-* variable overrides:
import_css/get_css_content in src/api.rs and src/settings.rs store and
serve the raw content unmodified (no sanitization or selector scoping),
and applyCustomThemeCss injects it as a plain unscoped <link> tag — a
stylesheet with e.g. `flex-direction`/`font-size` rules on real selectors
applies exactly as authored, alongside the required --c-* declarations.
