Aleix Conchillo Flaqué 675b7df408 Add tones to OutputDTMFFrame and simplify DTMF frame hierarchy

Introduces a new `tones` field on `OutputDTMFFrame` and
`OutputDTMFUrgentFrame` for sending multi-digit DTMF sequences and
deprecates the existing single-key `button` field. When only `button`
is set, it is used as a single-character `tones` string for backward
compatibility.

`DTMFFrame` is kept as an empty marker class so both input and output
DTMF frames can still be identified via isinstance. `InputDTMFFrame`
keeps its required `button` field (single keypress semantics).

The Daily-specific `DailyOutputDTMFFrame` and
`DailyOutputDTMFUrgentFrame` frames no longer need to override
`button` and simply add `session_id` and `digit_duration_ms`, which
are forwarded to Daily's `send_dtmf` as `sessionId` and
`digitDurationMs`.

The base output audio fallback now iterates `tones` and generates a
tone per character; LiveKit's native DTMF path sends `tones[0]` since
its API is single-tone.

Raw Blame History

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 tones field to OutputDTMFFrame and OutputDTMFUrgentFrame for sending multi-digit DTMF sequences (e.g. "123#"). Valid characters are the values of KeypadEntry.
Added DailyOutputDTMFFrame and DailyOutputDTMFUrgentFrame frames. In addition to the inherited tones, they accept session_id and digit_duration_ms, which are forwarded to Daily's send_dtmf as sessionId and digitDurationMs.
