Aleix Conchillo Flaqué d8b0e78bc8 Represent DTMF sequences as list[KeypadEntry] via buttons field

Replaces the string-based `tones` field with a type-safe
`buttons: list[KeypadEntry]` on `OutputDTMFFrame` and
`OutputDTMFUrgentFrame`, matching the existing singular `button`
field on `InputDTMFFrame`. A `from_string` classmethod builds the
list from a dial string like `"123#"` (invalid characters raise
ValueError from the `KeypadEntry` constructor).

The base output audio fallback now iterates `frame.buttons`
directly, LiveKit sends `frame.buttons[0].value`, and the Daily
transport joins the button values into the single string Daily's
`send_dtmf` expects.

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 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 and digit_duration_ms, which are forwarded to Daily's send_dtmf as sessionId and digitDurationMs.
