[FIX] : handle null room in contextual bar overflow interactions

[not-meet]

Issue #66

Acceptance Criteria fulfillment

• Contextual bar overflow interactions should open the respective modals

Cause!

• Contextual bar interactions provide room as null
  The check room === undefined only catches undefined, not null
• This caused the room to remain null, leading to "Cannot read properties of null (reading 'id')" error when trying to open modals

Proposed changes

Screencast.from.2026-02-12.02-16-40.webm

Changed from strict equality check (=== undefined) to truthy check (!room)
!room evaluates to true for both null AND undefined
