refactor(tenancy): simplify team table + move actions to edit modal

Reverts the expandable sub-row design back to a clean one-row-per-member
table. All per-store management now happens inside the edit modal.

Table: simple 4-column layout (Member | Stores & Roles | Status | Actions)
with view + edit buttons. Store badges show orange for pending stores.

Edit modal enhanced with per-store cards showing:
- Store name, code, and status badge (Active/Pending)
- Role dropdown + Update button (for active stores)
- Resend invitation button (for pending stores)
- Remove from store button
- "Remove from all stores" link at bottom

Removed: expandedMembers, flattenedRows, toggleMemberExpand,
resendStoreInvitation, resendInvitation (member-level).
Added: resendForStore, removeFromStore (work inside edit modal).
