QA: run_qa v1.6 form + ExplicitImports

Convert test/qa/qa.jl from the hand-rolled Aqua/JET/ExplicitImports body to
SciMLTesting v1.6 run_qa with explicit_imports = true.

ExplicitImports findings (all 6 checks now run):
- all_qualified_accesses_via_owners: FIXED by extending Base.rand/Base.randn
  instead of Random.rand/Random.randn (rand/randn are owned by Base; Random
  only re-exports them). Random.randexp / Random.rng_native_52 / Random.default_rng
  are genuinely Random-owned and left as-is.
- all_qualified_accesses_are_public: ignore default_rng and rng_native_52, both
  Random stdlib internals (not public in Random): default_rng is the standard
  default-RNG accessor; rng_native_52 is extended for the PassthroughRNG sampler
  chain. No way to make a stdlib's own non-public names public.
- no_implicit_imports, no_stale_explicit_imports, all_explicit_imports_via_owners,
  all_explicit_imports_are_public: pass with no changes.

No @test_broken markers needed (none existed; 0 hard fails after the above).

Deps (test/qa/Project.toml): SciMLTesting compat -> "1.6"; drop ExplicitImports
(transitive via SciMLTesting) and Random (qa.jl no longer uses it); keep Aqua
(ambiguities child-proc needs it a direct dep), JET (JET runs), SafeTestsets
(run_tests @safetestset wrapper needs it loadable in the QA env), Test.

Verified locally vs released SciMLTesting 1.6.0 (no dev-from-branch):
QA group 18/18 on Julia 1.10 (lts) and 1.12 (release); Core 3/3 on 1.10.
