Refactor the voice recording and playback systems to improve efficiency, reduce latency, and enhance Docker build performance.
- **Infrastructure**: Optimize Dockerfiles using build mounts for pnpm cache and reorder layers for better caching of dependencies and build tools.
- **Backend/Gateway**:
- Refactor `broadcast` module to use a generic event-based system instead of hardcoded functions.
- Simplify voice recording logic by merging metadata and segment management into a unified `segment.ts`.
- Optimize audio downsampling in `streamSetup.ts` using `Int16Array` views for better performance.
- Implement `withFallback` utility for more robust Redis/Database command execution.
- **Frontend**:
- Optimize audio playback visualization using pre-computed level shapes and efficient RMS calculation.
- Reduce latency in voice commands by prioritizing WebSocket communication over HTTP.
- Improve base64 encoding efficiency in audio transmission.
- **General**:
- Add default value for `ADMIN_PASSWORD` in shared config.
- Fix Docker healthcheck to use `127.0.0.1` instead of `localhost`.
- Standardize MessageRecord types — single source of truth from @bete/shared
- Clean up config: remove unused GUILD_ID/TEXT_GUILD_ID/TEXT_CHANNEL_ID, fix WEBSERVER_PORT default (3001), remove default admin password
- Move mascot_chat_messages table to Drizzle schema with proper migration
- Remove runtime DDL (CREATE TABLE IF NOT EXISTS) from mascot-chat repository
- Remove phantom analytics/ module from documentation
- Add better-sqlite3 dependency to root devDependencies
- Replace 'as any' casts with proper type assertions across AI moderation
- Add error logging to silent catch blocks in LLM client
- Apply Biome formatting and import organization

Migrate configuration validation and core moderation types from individual services to the `@bete/shared` package to ensure consistency across the monorepo.
- Move `AppConfig` and moderation-related interfaces to `packages/shared`.
- Replace service-specific Zod schemas with the centralized shared configuration.
- Refactor `services/backend` and `services/discord-gateway` to consume shared config and types.
- Remove redundant type definitions and local configuration logic in services.
- Update `packages/shared` exports to include new `config` and `moderation-types` modules.
- Clean up unused files and deprecated utility functions in `packages/shared`.
