feat: Multi-guild support implementation

- Added multi-guild support with comma-separated AllowedGuildIDs config
- Per-guild embed tracking with isolated state
- Per-server action locking to prevent race conditions across guilds
- Cross-guild embed updates after power actions
- Debug logging for embed update triggers
- Fixed resource usage field formatting (brackets now properly closed)
- Updated config.ini.sample, generate_config.py for backward compatibility
- Updated README.md with multi-guild documentation
- Updated tests for multi-guild support
