i18n polish + Swedish wired + roadmap slim + AppImage 1.2.4.1-beta

## i18n

- Swedish (sv) wired end-to-end: `MESSAGE_CATALOG` in `provider.tsx` now imports `sv/common.json`; `SUPPORTED_LANGUAGES` reordered as English + alphabetical native and all eight locales marked complete.
- Settings → Interface language: the per-locale status cards grid is retired now that all eight locales are populated end-to-end; the dropdown selector is the only control.
- CLI change-language dialog (`scripts/menus/config_menu.sh`) picks up Swedish and matches the Monitor ordering.
- Spanish catalog: label polish across the dashboard — *VM y LXC activos* / *11 VMs* / *11 detenidos*, LXC modal tabs shortened to *App / Actualiz. / Montajes / Copias*, *Limpiar / Cerrar* replacing the wrong *Claro / Cerca* in terminal controls, *En ejecución / Ejecutar* replacing the literal *Correr*.
- Cross-locale normalisation across ES / DE / FR / IT / PT / SK / SV: *OK* / *Proxmox System Dashboard* / *Warn* labels stay consistent, *AVG / MAX / MIN* kept verbatim as universal abbreviations so the stats row no longer overflows.
- Tailscale brand preserved verbatim across ES / FR / IT / PT — previous machine-translated variants like *"escala trasera"* / *"à grande échelle"* restored.

## Docs

- `ROADMAP.md` rewritten as a short invitation to the [ProxMenux Roadmap project board](https://github.com/users/MacRimi/projects/1). `ROADMAP.es.md` removed — it mirrored the same outdated version-milestone plan and the docs site keeps the Spanish surface for users who need it.
- `release.md` annotated with nine pending sections for the v1.2.4.1 beta cycle.

## AppImage

- `ProxMenux-1.2.4.1-beta.AppImage` replaces the previous `ProxMenux-1.2.4.AppImage`. Sidecar `ProxMenux-Monitor.AppImage.sha256` regenerated.
