Support replying to messages with voice recordings

[kalix127]

Content

Add support for replying to messages with a voice recording. The infrastructure already existed end-to-end (MediaSender.sendVoiceMessage() accepts inReplyToEventId), but the voice message presenter was not wiring it through.

Changes:

• Extract reply event ID from composer mode and pass it to mediaSender.sendVoiceMessage()
• Show the reply banner during voice recording/preview using the same TextInputBox wrapper
• Reset composer mode after sending a voice message reply
• Dismiss keyboard when voice recording starts
• Add unit test verifying reply event ID is passed correctly

Motivation and context

Closes #4053

Users could not reply to a message with a voice recording. Tapping "Reply" and then recording audio would send the voice message without the reply relation, and the reply banner would disappear during recording.

Tests

• Open a room, long-press a message, tap Reply
• Record a voice message - verify the reply banner stays visible during recording and preview
• Verify the keyboard dismisses when recording starts
• Send the voice message - verify the banner closes and the message appears as a reply in the timeline
• Send a voice message without replying - verify it sends as a normal message
