[Performance] Opening invite dialog causes full table re-render (Members Table Fully Refactored) #2806

Problem:
Opening the "Add Member" dialog triggers a full re-render of the entire MembersTable component tree. This was profiled with React Scan and confirmed at scale with 50 members/invitations.

Root Cause:
inviteDialogOpen state lives inside MembersTable. When the "+ Add" button is clicked, setInviteDialogOpen(true) updates state on the parent component, causing the entire table — all rows, cells, badges, and dropdowns — to re-render unnecessarily.
Same issue exists for changePasswordDialogOpen state.

Proposed Fix:
Basically Members Table Refactoring and Extract the invite button + dialog into an isolated InviteButton component so the open/close state is scoped locally and doesn't bubble up to MembersTable.

Proof (tested with 50 members) :
