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
