Pending invitations

Every POST /org/members invitation creates an org_invitations row in pending state, even when the invitee already has a Seismic account. Membership only exists once the invitee explicitly accepts. These endpoints are the receive side of POST /org/members.

Endpoints

GET /users/me/invitations
POST /users/me/invitations/{id}/accept
POST /users/me/invitations/{id}/decline

All three require a bearer token. An API key (which is itself org-bound) can't act on invitations to other orgs.

Email match is case-insensitive: an invitation to Acme@Example.com is visible to a user signed up as acme@example.com.
