feat: add Docker dev environment and fix logging/cashu-ts

- Add Dockerfile, docker-compose.yml, and .dockerignore for Bun dev container
- Fix sdkLogger to use logger.warn instead of logger.log for warnings
- Add proper warn method to logger (writes to file instead of console)
- Use console.log for daemon startup messages to keep them visible
- Update cashu-ts getDecodedToken call with explicit well-known-pubkeys
- Use proof.amount.toNumber() for updated cashu-ts Amount type
