Updated session handling and added configuration-time support across actions:

• Updated all actions and data sources to isolate each run's Firebase session, so one run can no longer pick up another connection's credentials or close a session another run is using
• Added inline action calling support across all actions for improved example output during configuration
• Added output schemas to the List Collections, Create Document, and List Documents actions for improved field mapping during configuration

• Masked the Private Key connection field so the value is hidden in the UI
• Renamed the connection label to Private Key

Updated spectral version

Added inline data sources for collections and documents to enhance data selection capabilities
