Beta cycle bundle over 1.2.4.1

- **VM/LXC modal** — PVE tags (dots on list cards, editable pills in modal with click-to-edit) using NVIDIA-style hash colour and SAPC contrast; Status tab redesign (single card, always-visible subsections, Edit button, autostart toggle, blue subsection icons); Backups and Firewall tabs now fill the full modal height with sticky headers/notes; stopped VMs no longer shift the metrics grid; mount-point card brightness unified across breakpoints.
- **Disks modal** — Overview / SMART / History / Schedule tabs adopt the VM/LXC modal size and the mobile icon-only tab pattern; SMART attributes table drops the 15-row cap and gains a sticky "View full SMART report" footer; Print/Save-as-PDF collapses to two icons in the report; loose i18n and layout follow-ups.
- **NVIDIA driver installer (#298)** — version picker cross-checks kernel + NVIDIA's Production/New Feature/Legacy branch classification (scraped from `nvidia.com/en-us/drivers/unix/`) + the PCI Device IDs of every host GPU, with a release-count heuristic to keep superseded production branches selectable while dropping Vulkan-beta ones; Recommended follows same-branch head when a driver is installed, Production Branch head on a fresh install; Hardware card now shows installed alongside available driver version.
- **Custom notifications (#297)** — `event_type: "custom"` accepts `title`/`message` at the root or nested under `data`; defensive strip of stray `[TITLE]`/`[BODY]` markers echoed by the AI enhancer.
- **App tab** — new "Exclude from the LXC updates counter" toggle; the CT's aggregate updates badge now sums OS packages plus registered apps (respecting the flag); Docs page updated; App suggestion no longer treats bare OS helper slugs (alpine/ubuntu/debian…) as installable apps.
- **i18n and copy** — Monitor UI available in EN / ES / DE / FR / IT / PT / SV / SK (thanks @vaso73) surfaced as the first entry in the What's New modal with a link to the contributor's profile; ES cleanup pass (`Historial`, `Velocidad de rotación`, `Consumo actual`, `Ejecutar`, `Eliminar`, `Activar`, `Ver contenido`, `Repuesto disp.`, `Registrar`, `Ocultar`, `Descartar`); redundant "Tip: search any Linux/Proxmox command" line removed from the terminal command search across all locales.
