RSB - Rumorix Social Button

Rumorix Social Button v1.5.0

- Added WoW 12.1.5 (Interface 120105) support while retaining 12.1.0 support.
- Audited the addon against the 12.1.5 API and security changes.
- Migrated Battle.net toast CVar reads to C_CVar.GetCVarBool with a compatibility fallback.
- Confirmed that the addon does not rely on APIs removed with Blizzard's deprecated compatibility modules.
- Hardened Quick Join popup suppression for lazily created or replaced toast frames.
- Added safer re-anchoring with coalesced next-frame updates.
- Added combat-safe deferral for position and visibility changes if Blizzard marks the Social button protected.
- Added PLAYER_ENTERING_WORLD recovery so initialization survives late Blizzard UI loading.
- Registered Edit Mode callbacks with an explicit callback owner.
- Kept Quick Join popup controls and Battle.net toast controls separate.
