perf(conpvp): zero-alloc trophy text via TrophyRank.LowerName (#2438)

Browse source 
## Summary

Phase 3.3 of the message-interpolation cleanup. Eliminates the `rank.ToString().ToLower()` two-allocation pattern in ConPVP trophy-award messages.

- Adds `TrophyRank.LowerName()` extension returning a static lowercase string per enum value via switch expression.
- Updates 10 call sites across Tournament, KingOfTheHill, DoubleDom, CTF, BombingRun (2 each - cash and no-cash branches).

The handler now appends a static interned string directly into the packet buffer; no `ToString()` formatter and no `ToLower()` allocation per call. Source comment in BombingRun.cs ("There is no formatting flag for Lowercase, we may need a custom interface to get rid of it") is now resolved at the call-site level.
