Guest user modal UI

[ericokuma]

Fixes UI inconsistencies in the Add guest users modal.

The project and access level dropdowns now match the height of the email input field for visual alignment. Additionally, the access level selector now uses checkbox items to provide clear visual feedback (checkmarks) for the selected role.

Checklist:

• Covered by tests
• Ran it and it works as intended
• Reviewed the diff before requesting a review
• Checked for unhandled edge cases
• Linked the issues it closes
• Checked if the docs need to be updated. If so, create a separate Linear DOCS issue
• Intend to cherry-pick into the release branch
• I'm proud of this work!

Note

Improves the AddGuestsDialog UI and selection behavior for guest invites.

• Updates dropdown trigger styling (min-h 32px, bg-white, text-sm, padding) to visually align with the email input
• Replaces hardcoded role items with ORG_ROLES_OPTIONS and uses Dropdown.CheckboxItem to show the selected role with a checkmark
• Keeps the project dropdown open after toggling a project selection; resets now also close both dropdowns

Great step to user management cleanup using ORG_ROLES_OPTIONS!

Note there is a small lint error. Otherwise LGTM
