perf: entity/skill/DBC/warden maps to unordered_map; fix 3x contacts scan

Browse source 
Entity storage: std::map<uint64_t, shared_ptr<Entity>> → unordered_map for
O(1) entity lookups instead of O(log n). No code depends on GUID ordering.

Player skills: std::map<uint32_t, PlayerSkill> → unordered_map.
DBC ID cache: std::map<uint32_t, uint32_t> → unordered_map.
Warden: apiHandlers_ and allocations_ → unordered_map (freeBlocks_ kept
as std::map since its coalescing logic requires ordered iteration).

Contacts: handleFriendStatus() did 3 separate O(n) find_if scans per
packet. Consolidated to single find_if with iterator reuse. O(3n) → O(n).
