perf: optimize secubox RPCD backend for faster dashboard loading

Performance improvements to reduce dashboard load time:

1. Cache opkg list across multiple module checks (avoid N opkg calls)
2. Pre-load UCI config once instead of per-module
3. Optimize get_dashboard_data() to use single loop for modules
4. Only check running status for installed modules
5. Use grep -E for single /proc/meminfo read instead of 2 greps
6. Remove redundant alert generation from dashboard data
7. Reuse loaded values instead of re-reading files

This reduces dashboard load time from 5-10 seconds to ~1-2 seconds
by eliminating redundant shell command executions.
