Fix Makefile to create speech.env automatically

- Add step in sync target to copy sample.env to speech.env if missing
- Ensures Makefile works from scratch without manual intervention
- Tested full deployment cycle: deploy -> voices -> test
- Successfully creates ~/uncloseai-speech directory
- Downloads voices with absolute paths
- Generates working TTS audio

Raccoon mission: Makefile is now fully self-sufficient!
