Notes:

This commit also includes several style and lint fixes required after
updating RuboCop:

- Removed redundant parentheses now detected by improved
  'Style/RedundantParentheses' (1.72 and 1.75.3).
- Replaced ternary expressions with logical OR when the ternary was
  returning 'true', as flagged by 'Style/RedundantCondition' (1.73).
- Adjusted block variables to resolve new 'Lint/ShadowingOuterLocalVariable'
  offenses (1.75), helping avoid future conflicts during upgrades with
  'rails app:updates'
