Fix ElevenLabs boolean query params and add enable_logging to HTTP service

Browse Source 
The enable_logging and enable_ssml_parsing URL params used truthy checks,
so False was treated the same as None (both skipped). Also, Python's
str(False) produces "False" but the API expects lowercase "false".

Additionally, add enable_logging support to ElevenLabsHttpTTSService
which was missing entirely.
