## Description
This PR adds support for sending voice messages (voice notes) through
the WhatsApp Cloud API. When agents record audio in Chatwoot, it is now
transcoded in the browser from WebM/Opus to OGG/Opus and sent with the
`voice: true` flag, so it appears as a native voice note bubble on
WhatsApp — not as a file/document attachment.
Closes#13283
**Key Changes:**
- Added `webmOpusToOgg.js` — a pure JS EBML parser + OGG page builder
that remuxes browser-recorded WebM/Opus audio into OGG/Opus entirely
client-side, with no server-side dependencies.
- Updated `AudioRecorder.vue` to use an explicit `mimeType` hint, proper
resource cleanup, and an `AUDIO_EXTENSION_MAP` for correct file
extensions.
- Renamed `mp3ConversionUtils.js` → `audioConversionUtils.js` and added
OGG conversion support via the new remuxer.
- Updated `ReplyBox.vue` to request OGG format for WhatsApp channels,
pass `isVoiceMessage` per-attachment, and handle recording errors with a
user-facing alert.
- Updated `MessageBuilder` to read the `is_voice_message` param and
persist it in attachment metadata.
- Updated `WhatsappCloudService` to:
- Normalize `audio/opus` → `audio/ogg` content type on ActiveStorage
blobs (works around Marcel gem re-detection).
- Send the `voice: true` flag when the attachment is a voice message
with `audio/ogg` content type.
- Use WhatsApp Cloud API `v24.0` for the attachment endpoint.
- Added `AUDIO_CONVERSION_FAILED` i18n key.
**How it works:**
1. The browser records audio as WebM/Opus (Chrome/Firefox default).
2. `audioConversionUtils.js` remuxes it to OGG/Opus using the pure-JS
`webmOpusToOgg` remuxer — no server transcoding needed.
3. The OGG file is uploaded with `is_voice_message: true` in the form
payload.
4. `MessageBuilder` persists `is_voice_message` in the attachment's
`meta` hash.
5. `WhatsappCloudService` normalizes the blob content type if needed,
then sends the attachment with `voice: true` so WhatsApp renders it as a
voice note.
## Type of change
- [X] New feature (non-breaking change which adds functionality)
## How Has This Been Tested?
1. Record a voice message in a WhatsApp Cloud conversation.
2. Verify the audio is transcoded to OGG (check file extension in the
attachment preview).
3. Verify the message arrives on WhatsApp as a voice note bubble (not a
document/file).
4. Send an image or document attachment and verify it still works as
before (no `voice` flag).
5. Send a regular (non-voice) audio file and verify it arrives without
the voice flag.

Last week, the WhatsApp API has started returning an error message for the voice notes, Unsupported Audio mime type audio/opus. Please use one of audio/ogg; codecs=opus, audio/mpeg, audio/amr, audio/mp4, audio/aac. This error began appearing on May 1. Even though there was no change in the files and content type, FB API started rejecting the file.
In this PR, we are converting the audio recordings from Wav to Mp3 from frontend itself.
