✨(frontend) add telephony info to meeting dialog with layout stability

Add telephony information display to the later meeting dialog while
preserving existing layout when telephony is disabled.

Prevent layout shift on modal close by collapsing all modal content
immediately when room becomes undefined.

Critical enhancement for users creating meeting links to have complete
connection information available.
