feat: add `scoreTarget ` as CIL feature for audits

[BioPhoton]

User story

Followup of #713 just for audits.

Acceptance criteria

• [ ] https://github.com/code-pushup/cli/issues/713
• [ ] the icons should be rendered correctly on all displays
  • [ ] terminal - The "✅" and "❌" characters cause layout issues in the terminal. I suggest "✓" and "✗" instead with chalk styling. e.g. chalk.bold(chalk.green('✓')) and chalk.bold(chalk.red('✗'))
  • [ ] readme - the "✅" and "❌" characters are used
  • [ ] JSON - n/a
  • ~portal - custom icons are used and they are already fine~

PR1 - CLI preparation

• [ ] extend auditSchema with targetScore
• [ ] rename applyMaxScoreAboveThreshold to scoreAuditWithScoreTarget and move it form plugin-coverage into utils
• [ ] adjust executePlugin to apply the new scoring logic after the normalization
• [ ] adopt categoryToGQL functions to convert the name back and the floating number back to boolean and mark it with a comment

PR2 - Portal model adoption

• [ ] accept a number from 0-1 for new property targetScore
• [ ] release portal-client

PR3 - CLI portal-client update

• [ ] adopt categoryToGQL functions for new type upload
• [ ] add targetScore styling to all places
  • [ ] for audits, scoreTarget means score is changed to perfect score, because it affects the category/group score calculation

• [ ] refactor plugin-coverage for the new targetScore shape

PR5 - Portal UI updates

• [ ] adopt score card for new targetScore logic
