feat: add config subcommand to manage API keys

[johnlanni]

Description

This PR adds a new config subcommand to the get-ai-gateway.sh script for managing LLM provider API keys.

Changes

New Commands

• config add --provider <provider> --key <api-key> - Add or update an API key
• config list - List all configured API keys (with masking for security)
• config remove --provider <provider> - Remove an API key

Features

• Support for all LLM providers (dashscope, deepseek, openai, claude, gemini, etc.)
• User-friendly provider name mapping (e.g., qwen → DASHSCOPE_API_KEY)
• API key masking in list output (e.g., sk-ab***cd12)
• Clear error messages and usage instructions
• Updated help documentation with examples

Examples

# List all configured API keys
./get-ai-gateway.sh config list

# Add or update an API key
./get-ai-gateway.sh config add --provider deepseek --key sk-xxx

# Remove an API key
./get-ai-gateway.sh config remove --provider deepseek

Benefits

• Easier management of API keys without manually editing config files
• Better security with masked display of sensitive keys
• Improved user experience for updating credentials

Testing

• Syntax check passed (bash -n)
• Command parsing works correctly
• Help documentation updated
