fix: Support both apk and opkg package managers for module detection

OpenWrt 25.12+ uses apk instead of opkg, causing module detection to fail.
Updated all package manager operations to support both:

**Changes:**
- check_module_installed(): Detect and use apk or opkg
- detect_real_modules(): Parse both apk and opkg output formats
- Version extraction: Use grep pattern matching for apk (portable)
- get_status(): Count modules from UCI config instead of RPCD scripts

**Detection Logic:**
- Check /usr/bin/apk → use apk commands (OpenWrt 25.12+)
- Check /bin/opkg or /usr/bin/opkg → use opkg (24.10 and earlier)
- Fallback to config file existence check

**Version Extraction:**
- apk: Extract X.Y.Z from "luci-app-name-X.Y.Z-rN" format
- opkg: Extract version from "package version" format

**Module Counting:**
- Now counts all modules from UCI config (14 total)
- Correctly detects installed packages (2 installed)
- Properly tracks running services (0 running)

Tested on OpenWrt 25.12.0-rc1 with apk package manager.
