feat: secrets management ui

[maxy-shpfy]

Description

Added a secrets management system that allows users to securely store and use sensitive information like API keys in pipelines. The implementation includes:

• A secrets management dialog accessible from the app menu
• Ability to add, update, and remove secrets
• A secret selection dialog for using secrets in pipeline arguments
• In-memory storage layer (to be replaced with a proper API later)
• Feature flag control to enable/disable the secrets functionality

Related Issue and Pull requests

Type of Change

• New feature
• Improvement

Checklist

• I have tested this does not break current pipelines / runs functionality
• I have tested the changes on staging

Screenshots (if applicable)

Test Instructions

1. Enable the "secrets" feature flag
2. Click the lock icon in the top navigation bar to open the secrets management dialog
3. Add a new secret with a name and value
4. Verify you can update and delete secrets

Additional Comments

The current implementation uses an in-memory storage layer with simulated async behavior. This will be replaced with a proper API integration in a future PR.
