deepgram: added request IDs to debug logs

[jjmaldonis]

Deepgram request IDs are necessary for investigating behavior at the request level. This commit adds DEBUG logs that print Deepgram request IDs when using Deepgram's STT or TTS.

Example log statements:

2025-11-17 12:25:54.894 | DEBUG    | pipecat.services.deepgram.stt:_connect:242 - DeepgramSTTService#0: Websocket connection initialized: {"headers": {'dg-project-id': 'e87380a0-834e-4f9f-b6ac-38324d90fef3', 'dg-request-id': '387b6093-f8f2-410e-b2e1-649033119e76'}}

2025-11-17 12:25:56.114 | DEBUG    | pipecat.services.deepgram.tts:run_tts:122 - DeepgramTTSService#0: HTTP connection initialized: {"headers": {'dg-model-name': 'aura-2-andromeda-en', 'dg-model-uuid': 'd40bb3c8-0122-484c-87db-943c415fb7d9', 'dg-char-count': '6', 'dg-project-id': 'e87380a0-834e-4f9f-b6ac-38324d90fef3', 'dg-request-id': '477b6af6-cfce-41b1-a8b3-9db6f03744b3'}}
