fix: support non-sequential server IDs in configuration

Previously, the config loader required sequential numbering (2, 3, 4...) for additional Proxmox/PBS endpoints. If a user had PROXMOX_HOST_2 and PROXMOX_HOST_4 (skipping 3), only endpoint 2 would be loaded.

This fix scans all environment variables to find any PROXMOX_HOST_N or PBS_HOST_N patterns, regardless of numbering sequence. Now users can have endpoints numbered 2, 5, 10, etc. and all will be properly loaded.

Fixes #96
