fix: resolve build and SQL errors for AzerothCore main (PlayerUpdates.cpp, SQL schema) [FaaFyfxR9WAQrL7FcAgEHJvztd8cVMxvjHRS55rw1nwH]

Fixes for Issue #27

This PR fixes two categories of errors preventing the module from compiling and running on the latest AzerothCore main branch.

Fix 1: C++ Build Errors (PlayerUpdates.cpp)

a) CinematicMgr (lines 73-77): _cinematicMgr is now stored by value in modern AzerothCore, not by pointer. Changed -> to . for all member accesses.

b) getHostileRefMgr() (line 404): Renamed to GetHostileRefMgr() (capital G) per modern AzerothCore API.

c) WeatherMgr (lines 1291-1298): The weather API has changed. WeatherMgr::FindWeather() and WeatherMgr::AddWeather() no longer exist. Replaced with WeatherMgr::GetWeatherData() + sWorld->FindWeather() pattern.

d) VisibleNotifier (lines 1605-1615): VisibleNotifier constructor now takes only (const WorldObject&). VISIBILITY_INC_FOR_GOBJECTS no longer exists. Replaced the two-pass notifier with a single-pass Acore::VisibleNotifier + Cell::VisitObjects call.

Fix 2: SQL Schema Errors

EntryChecker_RUN_FIRST.sql: Changed id1 column reference to id in the creature table SELECT query — the column is named id, not id1, in modern AzerothCore.

FactionFree.sql:

• All INSERT statements for the creature table changed \id1`to`id`` to match the actual schema.
• Both creature_template INSERT statements had the \scale`` column removed (column no longer exists in modern AzerothCore creature_template schema).
