Critical fixes:
- Release mutex before HTTP calls in GetStats() to prevent blocking
- Fix m.cmd race between Stop() and Wait() goroutine by capturing locally
- Add context support to GetStats() for proper request cancellation
High priority fixes:
- Add existence check in collectMinerStats() before operating on miners
- Add mutex-protected httpClient getter/setter for thread-safe test mocking
Changes:
- Miner interface now requires context.Context for GetStats()
- Stats HTTP requests timeout after 5 seconds (was 30s client default)
- All callers updated to pass context (service uses request context)

Security fixes:
- Remove hardcoded wallet address from CLI defaults (start.go, serve.go)
Pool and wallet are now required flags or must be provided explicitly
- Change file permissions from 0644 to 0600 for sensitive config files
Affects: xmrig config, profiles, settings, config cache
- Fix path traversal in untar() - now returns error instead of silently skipping
Concurrency fix:
- Fix race condition in GetStats() - was using RLock while writing m.FullStats
Changed to Lock/Unlock in both xmrig_stats.go and ttminer_stats.go
