feat(themes): sidebar notice when an installed theme has an update (#1041)

* feat(themes): sidebar notice when an installed theme has an update

Adds a dismissible sidebar pill (sibling of the What's New banner) shown
while an installed community theme has a newer version in the store. Clicking
opens Settings -> Themes; dismiss hides it until a new update changes the set.

The theme registry is now refreshed from source once per app launch instead
of only when the Theme Store tab is opened, so newly published themes and
updates surface without a manual refresh -- and feed this notice.

* docs: add CHANGELOG entry for PR #1041

* feat(themes): in-place update control on installed theme cards

Themes with a newer version in the store now show a centered update icon on
their card in Settings -> Themes; clicking it fetches and reinstalls in place.
Extracts the shared installThemeFromRegistry helper (fetch -> validate ->
install) used by both the store list and the card control, and surfaces the
full registry entry from useThemeUpdates so the card can update directly.
