server: add oai-compat /v1/audio/speech endpoint (#31763)

• server: add oai-compat /v1/audio/speech endpoint

• add e2e pytest

• server: share the s16 rounding, type speech form fields

The WAV writer of the audio helper truncates while pcm_f32_to_s16
rounds, so wav and pcm differ by one LSB. Both now round.

pcm_f32_to_s16 takes a pointer and a count and converts the TTS
bytes without an intermediate copy.

/tts and /v1/audio/speech parse their body with parse_tts_body, so
multipart fields such as speed get their type before the speech
conversion checks them.
