feat: add new parameters and flags to local engine configuration

This commit introduces new configuration parameters and their corresponding command-line flags for the local engine. The changes include:
- Adding "flash_attn" to ignored parameters
- Mapping UI parameters to CLI flags (e.g., cpu_threads → --threads)
- Expanding support for various model configuration options

These additions enhance the flexibility of the local engine by enabling fine-grained control over performance and behavior through both UI and CLI interfaces.
