feat(tauri, gui): Send event on changes to details, timelocks and tx_lock confirmations (#100)

- Send event when new swap state is inserated into database. The event only has the `swap_id` attached. The frontend then sends a request to the `get_swap_info` command to retrieve the updated version
- Send event when the Bitcoin lock transaction gets a new confirmation 
- A new `watcher` daemon runs contineously and sends an event when the timelock updated. The event has the the `swap_id` and the timelock attached
- Display logs on `ProcessExitedPage` (if swap was stopped prematurely)
- Rename `CliLogEmittedEvent` to `TauriLogEvent`
- Apply env_filter to tracing terminal writer to silence logging from other crates
- Add `.env.*` files in `src-gui` to `.gitingore`

Closes #93 and #12
