Talk to type with voice input
Added voice-to-text input so you can dictate messages instead of typing them.

- Added voice input capability to the message composer, letting you speak naturally and have your words transcribed in real time.
- Built visual feedback with a wave animation while listening, clear processing states, and simple confirm/cancel controls so you always know what's happening.
- Integrated voice input seamlessly into both the main chat input and the start message input, with transcript automatically appended to any existing text.
