feat(tenancy): add resend invitation for pending team members

New resend_invitation() service method regenerates the token and
resends the invitation email for pending members.

Available on all frontends:
- Merchant: POST /merchants/account/team/stores/{sid}/members/{uid}/resend
- Store: POST /store/team/members/{uid}/resend

UI: paper-airplane icon appears on pending members in both merchant
and store team pages.

i18n: resend_invitation + invitation_resent keys in 4 locales.
Also translated previously untranslated invitation_sent_successfully
in fr/de/lb.
