regression: correct E2EE availability hint for broadcast channels

[abhinavkrin]

Proposed changes (including videos or screenshots)

Updates the E2EE hint shown when creating a broadcast channel. The previous hint stated “Not available for broadcast channels,” which is incorrect. The hint is removed/updated so the E2EE toggle remains available and the message no longer contradicts the actual capability.

Issue(s)

Steps to test or reproduce

1. Open the Create new channel modal.
2. Enable Broadcast.
3. Verify the E2EE toggle remains available.
4. Confirm the hint no longer states “Not available for broadcast channels” (standard E2EE description or no hint is shown).

Pull Request Overview

This pull request addresses a regression where the E2EE (End-to-End Encryption) availability hint incorrectly stated "Not available for broadcast channels" when creating broadcast channels. The changes ensure that E2EE remains available for broadcast channels by updating the hint logic and removing the incorrect restriction message.

• Updated useEncryptedRoomDescription hook to make broadcast parameter optional and only show restriction for teams
• Removed broadcast parameter from calls to getEncryptedHint in channel creation modals
• Added comprehensive test coverage for the updated hook behavior
