Enhanced the base nym_http_api_client to reduce fragmentation and enable domain fronting:
- Added SerializationFormat enum for explicit JSON/bincode choice (no auto-detection)
- Added from_network() method to create clients from NymNetworkDetails with domain fronting
- Added with_bincode() builder method for explicit serialization configuration
- Set Accept header based on serialization preference
- Added deprecation paths for NymApiClient wrapper and nym_api::Client re-export
- Enabled domain fronting support via network defaults feature
This is part of a broader effort to consolidate HTTP client implementations across the codebase,
reducing ~500 lines of wrapper code and providing automatic domain fronting for censorship resistance.
