Pull request overview

This PR migrates Angular packages from the legacy @Output() decorator with EventEmitter to the modern output() function, following Angular's recommended migration path for output properties.

Changes:

• Migrated all @Output() decorators to use the new output() function across components and directives
• Updated template event handlers to use .emit() instead of .next()
• Updated type definitions to support both EventEmitter and OutputEmitterRef for backward compatibility
