Replace stylelint-config-recommended-scss with stylelint-config-standard

🎫 Ticket

Partially addresses #10545 (cc @anselmbradford)

🛠 Summary of changes

Updates Stylelint configuration to extend stylelint-config-standard-scss instead of stylelint-config-recommended-scss.

See CHANGELOG.md for more information:

• This is intended to bring the ruleset into closer alignment with the TTS Engineering CSS Coding Standards, which recommends the "standard" Stylelint rules.
• Many of these rules can be fixed automatically using Stylelint's --fix option.
• Some rules have been disabled to permit more flexibility in code arrangement, particularly rules affecting blank line enforcement with comments and Sass @-rules:
  • at-rule-empty-line-before
  • declaration-empty-line-before
  • rule-empty-line-before
  • scss/dollar-variable-empty-line-before
  • scss/double-slash-comment-empty-line-before
  • color-function-notation (due to Sass incompatibilities)

This also moves "reportNeedlessDisables": true from our project-specific configuration into the shared configuration. This will report inline configuration that disables rules unnecessarily, which is already enforced within this project.

📜 Testing Plan

Verify yarn lint:css passes.
