tts-xtts: coqui-tts needs click, which it does not declare

The venv built and then failed its import check with ModuleNotFoundError.
Verified the whole spec in a throwaway container first this time: with click,
'from TTS.api import TTS' works on torch 2.5.1+cu124 with transformers 4.46.3 —
the stack this image exists to provide.
