fix(tests): update hardcoded locale counts for Italian (it)

6 test files had hardcoded locale counts/lists that broke when
the Italian locale block was added:

- test_issue1488_composer_voice_buttons.py: added 'it' to LOCALES,
  replaced assert count == 9 with len(self.LOCALES)
- test_issue1560_password_env_var_lock.py: added 'it' to LOCALES
- test_1560_password_env_var_no_op.py: added 'it' to EXPECTED_LOCALES
- test_login_locale_parity.py: bumped floor from 9 to 10, added 'it'
- test_stage268_opus_followups.py: bumped floor from 9 to 10

(cherry picked from commit f5e42cec9b)
