qa(live-fixtures): swap apple+microsoft for veronica ballestrini

Removed:
  - test_apple_founders_grounded_and_names_steve_jobs
  - test_microsoft_founders_names_gates_and_allen

Added:
  - test_veronica_ballestrini_singer_october_birth

The veronica fixture is a stronger probe than the two it replaces:
  - entity-disambiguation among 8 same-first-name candidates
    (Landers, Guerin, Belmont, Wadley, Gamba, Doran, the
    disambiguation page, plus Ballestrini herself in the corpus)
  - multi-part question (who is she + when was she born)
  - niche personal-bio source (small article, harder to anchor
    than well-known commercial-tech bios)

Asserts: grounded + answer mentions Ballestrini + at least one
bio marker (country/singer/songwriter/Connecticut/Italian) + at
least one birth marker (October or 1991). Lands STRICT 1/1 in
JSON mode at the live test.

10/10 fixtures pass.
