* feat: implement file upload API snippet generation
Add proper two-step file upload support for API code generation:
- Detect file tweaks in ChatInput (string), File/VideoFile (path/file_path)
- Generate step-based cURL commands with separate copy buttons
- Fix ChatInput to use correct /api/v1/run endpoint with tweaks structure
- Update JavaScript and Python generators with proper endpoints and payloads
- Support dynamic node IDs and processedPayload values
- Implement step parsing UI for cURL with proper formatting

* fix: update JavaScript API snippet generator for native Node.js
Replace browser-based FormData approach with native Node.js http module
- Use built-in fs, http, and path modules instead of browser APIs
- Manually construct multipart/form-data payloads
- Add proper error handling and HTTP request helpers
- Support both ChatInput and File/VideoFile upload scenarios
- Maintain authentication header support

* fix: include output_type, input_type, input_value in File component cURL snippets
File/VideoFile components were missing the required payload fields when
generating cURL commands, causing flows to fail execution. Added the missing
fields to match the working pattern used in Chat Input components.

* fix: include output_type, input_type, input_value in Python and JavaScript File component snippets
File/VideoFile components were missing the required payload fields in Python
and JavaScript generators, matching the fix applied to cURL snippets.

* fix: use 'path' field for File components instead of 'file_id'
File components require the 'path' field from v2 upload response as an array,
not 'file_id'. Updated all three generators:
- Changed file_id to file_path variable extraction
- Changed "file_id": value to "path": [value] in tweaks
- Updated placeholder text for consistency
This fixes the "No files to process" error in File components.

- Simplified UI to show only 2 steps: uploads and execution
- Improved scrolling for better debugging experience
- Removed debug console.log statements
* fix: enhance API snippet generation with file upload support and consistent authentication
- Add multi-step file upload handling for ChatInput, File, and VideoFile components
- Implement automatic session ID generation using UUIDs across all snippets
- Ensure API key is always required in generated code (Python, JavaScript, cURL)
- Remove unused isAuth parameter from code generation logic
- Add comprehensive unit tests for file detection and code generation
- Support both Unix/Linux and PowerShell platforms for cURL commands

- Added `use_noop_session` fixture to facilitate testing without a database.
- Expanded `TestAgentComponent` with new tests for agent responses using the Calculator tool and validation across all OpenAI and Anthropic models.
- Updated `test_component.py` to include tests for message sending without a database, ensuring proper event handling and message integrity.
- Refactored existing tests for clarity and consistency.
* fix: enhance user retrieval logic in get_or_create_super_user and teardown_superuser functions
- Updated user retrieval in both functions to handle different result types from the database query, ensuring robustness against unexpected return values.
- Added checks for `first()` method and list type to improve error handling and maintainability.
* feat: add support for no-op database operations in settings
- Introduced `use_noop_database` configuration option to disable all database operations, controlled by the `LANGFLOW_USE_NOOP_DATABASE` environment variable.
- Updated the `use_noop_session` fixture to reflect the new environment variable for testing without a database.
* feat: implement NoopSession for database-less operations
- Added NoopSession class to provide a no-operation database session, allowing for testing and operation without a real database connection.
- Updated DatabaseService to utilize NoopSession when the `use_noop_database` setting is enabled, ensuring all database operations are disabled in this mode.
- Enhanced error handling and logging for session management, improving robustness in scenarios where the database is not in use.
* refactor: update import paths for NoopSession in test files
- Changed import path for NoopSession from `langflow.services.database.service` to `langflow.services.database.session` in both `test_agent_component.py` and `test_component.py`.
- This refactor improves code organization and aligns with recent changes in the project structure.
* feat: enhance NoopSession with result handling methods
- Added an internal _NoopResult class to the NoopSession, providing methods `first()`, `all()`, and `one_or_none()` for better handling of no-operation results.
- This enhancement improves the usability of NoopSession in testing scenarios by mimicking expected database query behaviors.
* refactor: improve logging for NOOP database session
- Changed the log level from warning to info for the NOOP database session message in the DatabaseService class.

* refactor: move NOOP database session logging to settings
- Removed the logging statement from the DatabaseService class and added it to the `set_use_noop_database` field validator in the Settings class.
- This change centralizes the logging for the NOOP database session, improving code organization and ensuring that the message is logged whenever the setting is applied.
* docs: Add heading and codeblock events for segment
* docs: Update scroll event names
* docs: improve capture of code block language
* docs: ensure code block language capture for mobile
