Refactor: Move selectors & routing logic to mining-proxy, remove selectors dependency

- Moved `selectors` and `routing_logic` modules to `mining-proxy`, isolating proxy-specific logic.
- Removed `selectors` dependency from `common_properties.rs`, `handlers/mining.rs`, `routing_logic.rs`, and related modules.
- Updated `IsUpstream` and `IsMiningUpstream` to remove `DownstreamSelector` and simplify their implementation.
- Removed unused imports related to `selectors` and `routing_logic` across multiple modules.
- Updated various `impl` blocks to match the new trait definitions without selectors.
- Fixed type inconsistencies in `on_open_standard_channel_success` and `on_open_standard_channel`.
- Ensured `UpstreamMiningNode` implements `HasDownstreamSelector` for proper selector access.
- Fixed `DownstreamMiningNode` compatibility by enforcing `Down = DownstreamMiningNode` where needed.
- Adjusted `config-examples/proxy-config-example.toml` to update upstream port.

This refactor improves modularity, makes mining-proxy self-contained, and eliminates unnecessary dependencies.
