feat(profile): port the cu-15 profile screen

 ### Added
 
+- Profile screen (cu-15): `ProfileViewModel` maps the signed-in
+  `AuthRepository.currentUser` into the identity block (name, email,
+  Google provider, avatar monogram); the P&L summary and game-activity
+  breakdown render as placeholders until the stats layer ships. Includes
+  the Loading skeleton, the Error retry card, the settings sheet
+  (`ModalBottomSheet`), deep links to KYC and the House Wallet, and Sign
+  Out, which tears down the session and clears the back stack to Login.
+- Shared `initialsOf` (avatar monogram) and `GameKey.iconRes` (game
+  glyph) helpers, extracted from the login, lobby and history screens so
+  the profile screen reuses them instead of duplicating.
 - Self-contained HMAC-SHA256 implementation under `cpp_engine/include/Sha256.h`,
   following FIPS 180-4 (SHA-256) and RFC 2104 (HMAC). Header-only, no external
   dependencies.
