Add web search base url

[amrit110]

This pull request refactors the generation of .env files to be more modular and maintainable by introducing helper functions for building each configuration section and categorizing keys by prefix. It also updates the validation logic and corresponding tests to ensure all required keys are present, including the new WEB_SEARCH_BASE_URL.

Key improvements and changes:

.env file generation refactor:

• Introduced helper functions (_add_embedding_section, _add_langfuse_section, _add_web_search_section, _add_weaviate_section, _add_other_keys_section) to modularize and organize the construction of different configuration sections in the .env file. These helpers categorize keys by their prefix for cleaner output. [1] [2]
• The main create_env_file function now filters out metadata fields, categorizes global keys, and uses the new helper functions to assemble the .env file, improving readability and maintainability.

Validation logic update:

• Updated validate_env_file to include WEB_SEARCH_BASE_URL as a required key, ensuring stricter and more accurate validation of generated .env files.

Test updates:

• Updated test fixtures in test_cli.py and test_utils.py to include the new required key WEB_SEARCH_BASE_URL, keeping tests in sync with validation requirements. [1] [2]
