Add MQ LuaRocks package repair

[Teichoui]

Summary

Adds RedFetch support for checking and repairing common MacroQuest LuaRocks packages after updates, matching MQ PackageMan's LuaRocks tree and versioned repository behavior.

Why

Some Lua scripts depend on common rocks such as lsqlite3 and luafilesystem. RedFetch should be able to verify the common packages exist on the user's MQ install and install missing packages using the same MQ LuaRocks layout PackageMan uses.

Details

• Adds redfetch lua fix to verify/install common MQ Lua packages.
• Runs the same check after successful watched updates when a MacroQuest path is configured.
• Adds a Settings maintenance button for manual repair from the TUI.
• Locates luarocks.exe in the MQ root.
• Uses the selected MQ modules/<jitVersion>/luarocks tree.
• Uses the matching versioned MQ LuaRocks repository, e.g. https://luarocks.macroquest.org/2.1.1774638290/.
• Keeps behavior aligned with MQ PackageMan rather than pinning a separate rock version.

Validation

• python -m pytest tests/test_lua_packages.py
• Verified in local MQ testing that PackageMan installed lsqlite3 0.9.6-1 and Bazaar loaded successfully.
