fix(ranked): use require for lovely version check

[stephenkirk]

Why

lovely is a preloaded module, not a global. The existing check (lovely and lovely.version) always evaluates to nil, so the version gate never actually works.

What this does

pcall(require, "lovely") to safely load the module in both ranked.lua and legacy_ranked.lua. Falls back to "" if lovely isn't available.

Test plan

• Correct lovely version — ranked enabled
• Wrong lovely version — shows version mismatch
• Same for legacy ranked
• SMODS version check still works independently

I actually make a commit for this last night and forgot to push the change, but it is live with PreRelease 2, and should be on main now
