feat(studio): Store + Cmd+K palette i18n (v0.27.0)

- Localize Store page: search hint, category and status filter
  chips (All / Published / Alpha / Planned / Installed),
  pluralized result count, hub-unreachable / no-matches empty
  states, featured strip header, store-card pills (installed /
  update / version), Install / Update / Details / Read docs /
  Uninstall / Not installable buttons, install-progress dialog,
  uninstall confirm dialog, install / uninstall toasts,
  open-browser failure toast.
- Localize detail-sheet sections: Tags, Required capabilities,
  Required host services, Screenshots, Documentation, Source.
- Localize docs panel: Load documentation button, fetching
  spinner copy, Open repository in browser button, friendly
  error mapping (not_found / no_docs / auth / network / parse).
- Localize Cmd+K palette: search hint, group labels (Pages /
  Modules / Store / Flows), keyboard hint footer, indexing /
  no-matches states, dynamic-hit copy ("installed module ·
  v{version}", "saved flow", "uncategorized"). Static page
  hits now flow through the localized "Pages" group; Settings
  entry uses the localized label and hint.

Status pill values ("published", "alpha", "planned") stay as
data-derived English strings since they map directly to the
store-index `status:` enum.
