feat: display app version in sidebar with GitHub release check

Both SearchBar and SearchModal now fetch and search pending devices by
IP, hostname, and service name. Selecting a pending result opens the
sidebar to the Pending tab and highlights the matching device.

 ## Proxmox LXC Install
 
-Run this **on the Proxmox host** — it creates a Debian 12 LXC container and installs Homelable inside automatically:
+You can now install Homelable with community-scripts (proxmox-VE) : 
+
+`https://community-scripts.org/scripts/homelable`
+
 
 ```bash
-bash <(curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/scripts/install-proxmox.sh)
-```
-
-Default container settings: 2 cores, 1 GB RAM, 8 GB disk, DHCP on `vmbr0`. Override before running:
-
-```bash
-CTID=150 RAM=2048 STORAGE=local-zfs bash <(curl -fsSL .../install-proxmox.sh)
-```
-
-The backend runs as a systemd service, the frontend is served via nginx on port 80.
-
-> To install manually inside an existing Debian/Ubuntu machine or LXC:
-> ```bash
-> bash <(curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/scripts/lxc-install.sh)
-> ```
-
-### Update (LXC)
-
-Run the update script inside the container (pulls latest code, rebuilds frontend, restarts services — `.env` and database are never touched):
-
-```bash
-sudo bash /opt/homelable/scripts/update.sh
-```
-
-Or directly from GitHub:
-
-```bash
-sudo bash <(curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/scripts/update.sh)
+bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/homelable.sh)"
