QA: drop now-public EI ignores (SciMLTesting 1.7 + base-lib public APIs)

SciMLTesting 1.7.0 runs the two public-API ExplicitImports checks
(check_all_qualified_accesses_are_public and
check_all_explicit_imports_are_public) only on Julia >= 1.11 and skips
them on the lts. Combined with the base-lib public-API releases
(SciMLBase 3.24.0, CommonSolve 0.2.9), the per-repo public-API ignore
entries this PR carried are now redundant.

Empty both public-API ignore-lists in test/qa/qa.jl: the previously
ignored AutoSpecialize (SciMLBase), init (CommonSolve), and solve
(CommonSolve) are all recognized as public on the registered releases,
so run_qa(...; explicit_imports = true) passes with no ei_kwargs at all.

Verified against registered releases (no dev of base libs; FVM dev'd
from this working tree):
- Julia 1.12 (public-API checks RUN): QA group 18/18 pass, 0 fail/
  error/broken; resolved SciMLTesting 1.7.0, SciMLBase 3.24.0,
  CommonSolve 0.2.9, ExplicitImports 1.15.0.
- Julia 1.10 lts (public-API checks skipped by SciMLTesting 1.7):
  QA group 16/16 pass, 0 fail/error/broken.

No names needed restoring; the ignore-lists are now empty.
