revert: drop requests/pytest bumps; keep only the 4 listed CVE fixes

CI broke under the wider upgrade, so narrow scope back to:
  - pygments 2.17.2 -> 2.20.0   (CVE-2026-4539)
  - pyasn1   0.6.2  -> 0.6.3    (CVE-2026-30922)
  - black    23.12.1 -> 26.3.1  (CVE-2026-32274)
  - pillow   12.1.1 -> 12.2.0   (CVE-2026-40192)

Reverted to main: requests 2.32.5, pytest 7.4.4, pytest-asyncio 0.23.8,
pluggy 1.4.0. The only forced transitive bumps are black 26.3.1's own
deps (pathspec 0.12.1 -> 1.0.4 and new pytokens 0.4.1).

55/55 tests pass under the resulting requirements.txt.
