fix(plugin-manager): address review feedback from @spiros132

(A) Replace all .replace("{placeholder}", value) string interpolation with
    native tr(key, { placeholder: value }) API — 11 call-sites across two files:

    AvailableTabContent.qml (3 sites):
    - installPlugin(): panel.installing, panel.install-success, panel.install-error
    - version display: panel.version-prefix concat → panel.version-display interpolation

    InstalledTabContent.qml (8 sites):
    - _addPluginToBar(): panel.already-on-bar, panel.add-to-bar-success
    - uninstallDialog description binding: panel.uninstall-dialog-description
    - uninstallPlugin(): panel.uninstalling, panel.uninstall-success, panel.uninstall-error
    - update button onClicked: panel.install-success, panel.install-error
    - version display: double version-prefix concat → panel.version-update interpolation;
      single version-prefix concat → panel.version-display interpolation

    New i18n keys added to all 17 locale files:
    - panel.version-display: "v{version}"
    - panel.version-update: "v{from} → v{to}"

(B) NTabView decision — Panel.qml left unchanged (StackLayout kept):
    NTabView uses implicitHeight for sizing and slide animation. The plugin-manager
    left column uses Layout.fillHeight: true with NScrollView children that have no
    meaningful implicitHeight — NTabView would collapse to zero height and produce
    broken animation. The existing NTabBar + StackLayout pattern is correct here.

- Bump version 1.0.0 → 1.0.1
