✨ feat: add gen-auth tool and refactor compose templates

Major refactor of Docker Compose configurations and tooling enhancements.

- ✨ Add `gen-auth` script for generating Tor Control Port credentials
- 🐳 Refactor Docker Compose templates:
  - Add native healthcheck configurations to all relay/bridge files
  - Standardize security capabilities (drop ALL, add SETUID/SETGID)
  - Remove verbose comments to streamline template usage
  - Update volume definitions for better data persistence
- 🔧 Update base dependencies:
  - Alpine Linux -> 3.23.0
  - Golang -> 1.25.5-alpine
- 🧹 Standardize ENV variable names across all configurations
