Keep inline-snapshot disabled when pytest runs in a terminal

`default-flags = ["disable"]` only covers runs whose stdout is not a
terminal. In a terminal outside CI the plugin fell back to its own
`default-flags-tui` default (`create`, `review`), stayed active, and the
locked version raised `AttributeError: ... has no attribute '_meta'` on
every `snapshot(...)` literal that spells the field as `_meta=`.

Set `default-flags-tui` to `disable` as well, so a plain `pytest` run
behaves the same in a terminal, in a pipe and in CI. Snapshots are still
updated with an explicit `--inline-snapshot=create` or `fix`.

Fixes #3544
