feat(proxmox): add journalctl endpoint without service; add limit parameter

Added new Proxmox journalctl endpoint `/journalctl/:node/:vmid` for viewing all
journalctl output without requiring a service name. Made the service parameter
optional across both endpoints.

Introduced configurable `limit` query parameter (1-1000, default 100) to both
proxmox journalctl and docker logs APIs, replacing hardcoded 100-line tail.

Added container status check in LXCCommand to prevent command execution on
stopped containers, returning a clear status message instead.

Refactored route validation to use pre-fetched IPs and improved References()
method for proxmox routes with better alias handling.
