fix: handle parenthetical qualifiers and multi-comma server names

Parse server names more robustly for sorting:
- "City, Country, Provider" → use second part as country
- "City, Country (1) (Hetzner)" → strip parentheticals from country
- "Frankfurt, Germany (FRA01)" → country is "Germany" not "Germany (FRA01)"
