fix(themes): unify input & dropdown focus borders across themes (#1052)

* chore(themes): drop the dead installs field from RegistryTheme

The store no longer reads install counts (the themes registry stopped
emitting them), so this optional field on RegistryTheme was unused.

* fix(themes): give dropdown border/shadow tokens a cascade default

--border-dropdown and --shadow-dropdown were set by only two themes and had
no base fallback, so dropdown/popover borders rendered without a themed value
in every other theme. Default them in the semantic cascade next to the other
menu tokens; themes that set them explicitly still override.

* fix(themes): unify input focus rings, drop the double border

Text inputs draw their own border + box-shadow focus ring, but the global
:focus-visible outline stacked a second ring outside it — a double border on
every field. Suppress the outline for text inputs centrally; the specificity
(0,1,1) beats the global ring but loses to the colour-blind-safe themes'
[data-theme] *:focus-visible (0,2,0), so those keep their stronger AAA ring on
every field by design — the header search now carries that ring on its cluster
there too. Align the few input classes that had a weaker or missing ring to the
shared border + 3px accent-dim standard.

* docs(changelog): add #1052 input/dropdown focus border fixes
