Add AI usage logs for Gemini and Whisper

- Migration + AiUsageLog model with tokens, duration, time, cost fields
- GeminiIntentService and GeminiVisionService log every API call
  with input/output token counts from usageMetadata and response time
- TelegramBotService logs Whisper calls with audio duration (from Telegram)
  and calculates cost at $1/second
- Whisper voice duration now passed from TelegramWebhookController
- Free text in Telegram now tries Gemini intent detection before showing menu
- /chat/ia-logs: Livewire component with summary cards + filterable table
- Whisper connection test button in config panel
- "Logs IA" link added to Chat/Bot nav section
