QA: Aqua/JET findings marked @test_broken pending fix

The grouped-tests QA group surfaced the following genuine Aqua/JET findings. They are currently wrapped as @test_broken in test/qa/qa.jl so the QA group runs green in CI; they should be fixed and un-broken.

Aqua (Aqua.test_all)

• deps_compat (extras): FunctionProperties does not declare a [compat] entry for the Pkg test extra. (Aqua.test_all(...; deps_compat=false) is used so the remaining Aqua sub-checks still run; the deps/compat check is @test_broken.)

JET (JET.test_package)

• 1 possible error found: Cassette.m is not defined: Cassette.m in overdub(ctx::Cassette.Context, ::typeof(nameof), args::Vararg) (Cassette/src/context.jl:286). The JET.test_package assertion is @test_broken.

All passing Aqua sub-checks remain enforced. These two checks should be fixed and the @test_broken markers removed (they will auto-flag via Test as "Unexpectedly Pass" once fixed).

Ignore until reviewed by @ChrisRackauckas.

Start in test/qa/qa.jl and inspect the @test_broken cases for Aqua.test_all and JET.test_package. Review the reported Pkg test-extra compatibility finding and the Cassette.m error at Cassette/src/context.jl:286, then run the grouped-tests QA checks. Done means both findings are fixed, the markers are removed, and all QA checks pass.
