feat: Update PulpUI to PatternFly 6

Summary

PatternFly 6 brings a fleet of a new components and upgrades following PatternFly 5. To enable the migration to React 19, PatternFly needs to be upgraded. A codemod has been generated by the RedHat team to convert most changes across automatically but some components might require manual intervention. In this case, it is proposed that more generic primitive components are designed so that they are reused throughout, avoiding multiple unique implementations.

Tasks

• Understand current dependency requirements for all @patternfly packages.
• Update Package Files: Bump @patternfly/patternfly, @patternfly/react-core, @patternfly/react-table to 6.6.1.
• Deploy @patternfly/pf-codemods to identity and convert deprecated functionality to new standards if possible.
• Manually migrate components, if they are unable to be updated by the codemod.
• Run Cypress test & run UI build steps.
• Document minor issues found for future attention within Github Issues.

Deprecated Components for manual migration

2. Select

Start by reviewing the current dependency requirements in the package files and the PatternFly 6 upgrade guide. Run the PatternFly codemod, then inspect the listed Modal, Select, Dropdown, Dropdown Toggle, and KebabToggle migrations for manual work. Done means the packages are at 6.6.1, deprecated functionality is migrated, and the Cypress tests and UI build pass.
