feat: enhance MCP tools and environment management

[maximedogawa]

• Updated the fetchMcpTools function to increase the timeout from 3000ms to 15000ms, improving reliability in fetching tools.
• Introduced a new mcpEnvHelpers.ts module to manage environment variables, including functions for identifying secret keys and building environment maps from form inputs.
• Refactored the AddServerForm and McpServerCard components to utilize the new environment management functions, enhancing the handling of API keys and other environment variables.
• Added passthrough environment handling in the tool engine, allowing for better management of environment variables associated with tools.
• Implemented new server routes for handling passthrough environment updates, improving the API's capability to manage tool-specific configurations.
