feat: add full argument support to account create command (#32)

Implement comprehensive non-interactive support for Safe account creation:

**account create**
- Add `--chain-id <chainId>` option to specify chain without selection prompt
- Add `--owners <addresses>` option supporting:
  - Comma-separated addresses: `0xabc,0xdef`
  - JSON array format: `["0xabc","0xdef"]`
  - Automatic validation and checksumming
- Add `--threshold <number>` option to set signature threshold
- Add `--name <name>` option to set Safe name
- Add `--no-deploy` flag to skip deployment prompt
- Add JSON output mode with `--json` flag including:
  - Safe details (name, address, EIP-3770 format, chain)
  - Configuration (owners, threshold, salt nonce)
  - Deployment status

All parameters maintain backward compatibility with interactive prompts when not provided.

### Example Usage

```bash
# Fully automated Safe creation
safe account create \
  --chain-id 1 \
  --owners "0x123...,0x456..." \
  --threshold 2 \
  --name production-safe \
  --no-deploy \
  --json

# JSON array format for owners
safe account create \
  --chain-id 137 \
  --owners '["0xabc...","0xdef..."]' \
  --threshold 2 \
  --name polygon-safe \
  --json
```

This completes Phase 3 of the non-interactive CLI enhancement, providing full automation support for all account management commands.
