fix: address code review issues in granular project access

- listProjects in members page load now uses .catch(() => null) so a
  permissions or network error does not break the entire page
- projectAccessSelector disables "Add project" when projects list is
  empty (prevents unusable required dropdown row)
- createMember resets orgProjects on modal close so subsequent opens
  fetch a fresh list instead of showing a stale one
- edit modal init effect now checks supportsProjectRoles before setting
  accessType to 'specific', preventing a silent role re-submission when
  the org plan is downgraded below the project-roles threshold
