Remove unused disconnect method and integrate configuration into server

- **app/relay/disconnect.go**:
  - Deleted unused `disconnect` method that was no longer referenced in code.

- **app/relay/server.go**:
  - Integrated server configuration (`config.C`) directly into the `Server` struct.
  - Refactored `authRequired` and `publicReadable` fields to derive from the configuration.

- **app/relay/server-impl.go**:
  - Removed references to the obsolete `disconnect` method.
  - Updated methods to retrieve authentication and readability settings from configuration.

- **app/relay/handleRelayinfo.go**:
  - Adjusted `handleRelayinfo` to use `config.C.AuthRequired` for showing relay limitations.

- **app/config/config.go**:
  - Added default values for the `SpiderSeeds` field for consistent initialization.
  - Logged configuration details upon loading for better debugging visibility.

- **interfaces/server/server.go**:
  - Removed `Disconnect` method from `server.I`, as it was no longer needed.

- **main.go**:
  - Modified `relay.ServerParams` to pass the configuration as a pointer (`config.C`).
  - Simplified initialization by removing redundant fields replaced by configuration integration.

- **protocol/socketapi/handleEvent.go**:
  - Standardized and clarified comments for parameter descriptions.
