Integrations - redesign admin UI

[AmaLuci]

Goal
Reorganize and simplify the configuration of external integrations and data sources used by the PBX and CTI.

This section includes:

• Phonebook sources (external contact sources and synchronization)
• Video sources (IP cameras and intercoms)
• Parameterized URLs (external integrations triggered by call events)
• Customer cards configuration (where applicable)
• External services integrations (e.g. TTS/STT)

Design goals

• replace the current “Applications” concept with a clearer and more consistent structure
• simplify setup and management of external data sources (e.g. phonebook)
• improve clarity of integration points with external systems (e.g. CRM via URLs)
• ensure scalability for future integrations
