Aleix Conchillo Flaqué b11a3bc43f Add method field to Daily DTMF output frames
Lets callers specify Daily's DTMF delivery method (e.g. "rfc2833"
or "info") alongside `session_id` and `digit_duration_ms`. Forwarded
to Daily's `send_dtmf` as `method`.

- Added `DailyTransport.send_dtmf()` to expose the Daily call client's DTMF sending capability, enabling applications to send tones during a call (e.g. IVR navigation).
- Added `buttons` field to `OutputDTMFFrame` and `OutputDTMFUrgentFrame` for sending multi-key DTMF sequences as a `list[KeypadEntry]`. Use `OutputDTMFFrame.from_string("123#")` (or the equivalent on `OutputDTMFUrgentFrame`) to build one from a dial string.
- Added `DailyOutputDTMFFrame` and `DailyOutputDTMFUrgentFrame` frames. In addition to the inherited `buttons`, they accept `session_id`, `digit_duration_ms` and `method`, which are forwarded to Daily's `send_dtmf` as `sessionId`, `digitDurationMs` and `method`.
