fix(security): harden TLS, timeouts, validation, logging, and token generation
- Default TLS verification on, opt-in UPKEEP_INSECURE_SKIP_VERIFY
- Alert webhooks use 10s timeout client, close response bodies
- URL input validates http/https scheme for HTTP monitors
- Stdlib logs route to stderr instead of discard
- Panic on crypto/rand failure in token generation
- Cluster startup warnings for non-HTTPS and missing secret
- Replace demo SMTP creds with obvious placeholders
- Color-coded log entries and scroll hints in logs tab
