feat: v0.0.1 - Groq provider, timezone, journal context, test connection, task logging

Added:
- Groq AI provider (free, fast with llama-3.3-70b-versatile)
- Timezone setting (22 timezones)
- Journal context: include previous journals (3/7/14/30 days)
- Test connection button for AI providers
- Per-provider settings (API key, model, base URL remembered)
- Detailed task logging (full prompts and responses)
- Tasks page with expandable details
- Progress modal with steps and AI output details

Fixed:
- Groq API endpoint (https://api.groq.com/openai/v1/chat/completions)
- Ollama baseUrl leaking to other providers
- Database schema references
- Proper Prisma migrations (data-safe)

Changed:
- Default AI: OpenAI → Groq
- Project renamed: TotalRecall → DearDiary
- Strict anti-hallucination prompt
- Docker uses prisma migrate deploy (non-destructive)
