Update crypto documentation with accurate configuration and remove tutorials

- Document actual resource requirements from production systems
- Fix fee documentation: fee buffers are for quotes, not wallet reserves
- Clarify perfect accounting to quote amounts in atomic units
- Remove generic curl/API tutorials, keep Make commands
- Add dust prevention benefit of exact amount sweeping
- Update Makefile targets to match what actually exists

+**Auto-Sweep System:**
+
+The system uses perfect accounting to the quote amount - sweeping exactly what the customer paid (including fee buffers). Quotes are calculated in atomic units (koinu) for precision. After confirmation, the full payment amount is swept to cold storage with network fees paid from the balance. Each shop's funds are swept to their configured cold wallet address immediately after confirmation. This approach prevents dust accumulation in the hot wallet.
