fix(Fix_unreachable_netservices_v2): v16 compatibility fixes

[Joeboyc2]

Summary

Two issues prevent Fix_unreachable_netservices_v2 from building under WLED v16:

• Missing libArchive: false in library.json — the v16 build system requires "build": {"libArchive": false} in every usermod's library.json. Without it the build fails immediately with ERROR: libArchive=false is missing on usermod(s).

• serializeConfig() no longer has a no-argument overload — v16 changed serializeConfig() to require a JsonObject parameter. The correct no-argument replacement for saving config to the filesystem is serializeConfigToFS().

Test plan

• Fix_unreachable_netservices_v2 compiles cleanly in an ESP8266 build environment with both fixes applied
• Verified serializeConfigToFS() is the correct equivalent — it allocates the JSON document internally and calls serializeConfig(root) + writes to LittleFS

Walkthrough

This PR fixes the FixUnreachableNetServices usermod by ensuring periodic configuration updates are persisted to the filesystem instead of kept in memory. The library manifest is also updated to control build archiving behavior.
