chore: migrate to new version + fixed several critical bugs

- Migrated project to latest Telegram iOS base (v12.3.2+) - Fixed circular dependency between GhostModeManager and MiscSettingsManager - Fixed multiple Bazel build configuration errors (select() default conditions) - Fixed duplicate type definitions in PeerInfoScreen - Fixed swiftmodule directory resolution in build scripts - Added Ghostgram Settings tab in main Settings menu with all 5 features - Cleared sensitive credentials from config.json (template-only now) - Excluded bazel-cache from version control
