When an inbound voice call ends, the conversation bubble now (1) renders
an inline audio player as soon as Twilio finishes the recording and (2)
shows the call duration alongside "Call ended" so the agent gets the
at-a-glance summary without opening the recording.

and
https://linear.app/chatwoot/issue/PLA-119/duration-of-the-call-is-not-visible-on-the-chat-bubble
## How to test
1. Set up a Twilio voice inbox and trigger an inbound call.
2. Answer the call from an agent, talk for a few seconds, then hang up.
3. As soon as the call ends, the bubble should read **"Call ended —
0:NN"** (where NN is the call duration in seconds).
4. Wait a few seconds for Twilio to finish processing the recording
(usually <30s after hangup).
5. The same bubble should now show an inline audio player below the
duration. Press play; the recording should be audible.
6. Refresh the page — both the duration and the player should still be
there.
7. End a second call on the same conversation — its bubble should get
its own duration + player, independent of the first.

### Description
Inbound voice calls now route ownership cleanly: the call widget is
hidden from agents who aren't the conversation assignee, the first agent
to pick up becomes the assignee, and any later join attempt by another
agent is rejected with a clear "<agent> is already handling the call."
alert.

### How to test
1. As Agent A and Agent B, open the dashboard for the same voice inbox
in two browsers.
2. Place an inbound call to the inbox with the conversation
**unassigned** — both agents should see the call widget.
3. Have Agent A click **Join**. Agent A's widget transitions to the
active call; Agent B's widget disappears (conversation is now assigned
to Agent A).
4. While the call is in progress, attempt to join from a third agent
(e.g., via the bubble in the conversation timeline) — the join is
rejected with the toast `Agent A is already handling the call.`
5. Resolve the conversation, then place a second call to a conversation
that is already manually assigned to Agent A — only Agent A sees the
widget; nobody else does.
6. Race test: trigger two near-simultaneous join attempts (two agents
click Join within a few hundred ms of each other) — exactly one wins;
the other gets the conflict alert.

Twilio voice now uses first-class `Call` records as the source of truth
for call state, instead of storing it on
`conversation.additional_attributes` and `conversation.identifier`. Each
call gets its own record, its own `voice_call` bubble matched by
`call_sid`, and its own conference name keyed off `Call.id`. Multiple
calls on the same conversation (for `lock_to_single_conversation`
inboxes) now work correctly, and the conversation card stays in sync
with the real latest message.

Voice calling is now a capability on the existing TwilioSms rather than
a separate Voice model. A single Twilio phone number handles both SMS
and voice calls through one inbox.
Fixes
https://linear.app/chatwoot/issue/CW-6683/add-voice-calling-as-a-capability-on-twilio-sms-channel
and https://linear.app/chatwoot/issue/PLA-120/add-the-support-for-sms
**What changed**
- Replaced Channel::Voice with voice_enabled flag on Channel::TwilioSms
- Added voice_enabled, twiml_app_sid, api_key_secret columns to
channel_twilio_sms table
- Dropped channel_voice table (no production data)
- All voice logic lives in Enterprise layer via
prepend_mod_with('Channel::TwilioSms')
- Added Voice settings tab on Twilio SMS inbox settings to
enable/disable voice
- Validates Twilio number voice capability before provisioning
- Teardown service cleans up TwiML app and credentials when voice is
disabled
- Frontend voice detection uses isVoiceCallEnabled() /
getVoiceCallProvider() helpers — extensible to future providers
- Gated by channel_voice feature flag
**How to test**
1. Enable feature flag:
Account.find(<id>).enable_features('channel_voice')
2. Create voice inbox: Inboxes → Voice tile → enter Twilio credentials →
verify incoming/outgoing calls and SMS work
3. Enable voice on existing SMS inbox: Inboxes → select Twilio SMS inbox
→ Voice tab → toggle on → provide API key credentials → verify calls
work
4. Disable voice: Voice tab → toggle off → verify TwiML app is deleted,
credentials cleared, SMS still works
5. Re-enable voice: Toggle on again → must provide api_key_secret again
→ new TwiML app provisioned
