## Description
This PR introduces dedicated color tokens for the floating voice call
widget instead of reusing generic design tokens. This allows the widget
to maintain a distinct dark-card appearance across both light and dark
themes.
Adds the following tokens and applies them to `CallCard`:
* `--call-widget`
* `--call-widget-border`
* `--call-widget-text`
* `--call-widget-sub-text`

## Linear Ticket
https://linear.app/chatwoot/issue/CW-7261/call-window-theme-alignment
## Description
Updates the call window's reject/end button to use the hang-up handset
icon (the same handset as the accept button, rotated) instead of the
phone-with-X, matching the design.

## Linear ticket
https://linear.app/chatwoot/issue/CW-7187/voice-calls-followup-tasks
## Description
Improvements to the WhatsApp voice-calling experience plus a cheaper,
more accurate audio-transcription model.
- First-time callers now get a real name. An inbound WhatsApp call
creates the contact from the caller's WhatsApp profile name instead of
the bare phone number.
- Clear, consistent call attribution. Call bubbles show a unified
"Handled by {agent}"
- Cleaner call widget. The dismiss (✕) button is shown only for incoming
calls
- WhatsApp calling for manual inboxes. voice_calling_supported? now
covers any whatsapp_cloud inbox
- Transcription: whisper-1 → gpt-4o-mini-transcribe.

## Summary
Frontend for WhatsApp Cloud Calling: header / contact-panel call
buttons, ringing widget, accept/reject/hangup, mute, in-bubble audio
player + transcript, recording-on-hangup upload, mid-call reload
warning. WebRTC is browser-direct to Meta — no media server bridge.
## Closes
- https://linear.app/chatwoot/issue/PLA-150
## How to test
Requires backend support — the controller, services, model changes, and
routes ship in **#14334** (`feature/pla-150`). Merge / deploy that first
(or simultaneously); the FE alone won't function without those
endpoints.
Then on staging, for a WhatsApp Cloud + embedded-signup inbox with the
new \`Configuration → Enable voice calling\` toggle ON and webhook
registered:
1. **Outbound** — open a conversation, click the phone icon in the
conversation header (or contact panel), grant mic, your phone rings,
answer, audio both ways, hang up. Recording + transcript land in the
bubble within ~10s.
2. **Inbound** — call the business number from your phone. The
FloatingCallWidget appears bottom-right with caller name. Click accept,
audio both ways, hang up. Recording + transcript appear.
3. **Mute** — during an active WhatsApp call, click the mic icon next to
hangup. Speech stops reaching Meta until you click again.
4. **Mid-call reload guard** — try `Cmd-R` during an active call;
browser shows a confirm prompt.
