Subject: [PATCH] [Minor] Migrate lua_fuzzy.lua from tableshape to lua_shape

Replace tableshape with lua_shape for fuzzy policy schemas:
- Convert ts.number + ts.string / tonumber to T.transform + T.one_of
- Convert ts.array_of to T.array
- Convert ts.boolean to T.boolean()
- Convert ts.shape to T.table with open option support

No functional changes, luacheck passes.
