This commit adds `serde` dependency and derives `Serialize` trait for `Score` types. This is necessary for serialization and deserialization of these types, which is required to display Scores to various user interfaces
- Added `serde` dependency to `harmony_types/Cargo.toml`.
- Added `serde::Serialize` derive macro to `MacAddress` in `harmony_types/src/lib.rs`.
- Added `serde::Serialize` derive macro to `Config` in `opnsense-config/src/config/config.rs`.
- Added `serde::Serialize` derive macro to `Score` in `harmony_types/src/lib.rs`.
- Added `serde::Serialize` derive macro to `Config` and `Score` in relevant modules.
- Added placeholder `todo!()` implementations for `serialize` methods. These will be implemented in future commits.
- Implemented `OKDLoadBalancerScore` and integrated it as a `FrontendScore`.
- Added `FrontendScore` trait for TUI displayable scores.
- Implemented `Display` for `OKDLoadBalancerScore`.
- Updated `ScoreListWidget` to handle `FrontendScore` types.
- Included load balancer score in the TUI.
Introduce the `Topology` trait to ensure that `Maestro` can compile-time safely bind compatible `Scores` and `Topologies`. This refactoring includes updating `HarmonyTuiEvent`, `ScoreListWidget`, and related structures to work with generic `Topology` types, enhancing type safety and modularity.
Add a .gitignore file to exclude target, private_repos, and log directories. Update TftpScore and HttpScore file paths in `main.rs` to use relative paths from the project root. Modify `HarmonyTUI` initialization in `lib.rs` to create log directory if it doesn't exist before setting the log file path.
