SEC-WEB-27: Replace weak email.includes('@') check with RFC 5322-aligned
programmatic validation (isValidEmail). Uses character-level domain label
validation to avoid ReDoS vulnerabilities from complex regex patterns.
SEC-WEB-28: Replace unsafe 'as WorkspaceMemberRole' type casts with
runtime validation (toWorkspaceMemberRole) that checks against known enum
values and falls back to MEMBER for invalid inputs. Applied in both
InviteMember.tsx and MemberList.tsx.
Adds 43 tests covering validation logic, InviteMember component, and
MemberList component behavior.
