v2.1.1

A patch release fixing two multi-tenant issues surfaced in a real @payloadcms/plugin-multi-tenant install. No breaking changes — plain single-tenant installs are unaffected.

Fixed

• Customer search is now tenant-scoped. The /api/reservation-customer-search endpoint (used by the reservation customer picker) restricts results to the selected tenant — read from the tenant cookie — whenever the customers collection carries the multi-tenant tenant field. This prevents picking a customer from another tenant, which would otherwise fail on save with a tenant mismatch. Plain single-tenant installs are unaffected (no tenant field / no cookie ⇒ no scoping).
• Flexible-duration reservations can be saved from the admin UI. The reservation endTime field was unconditionally read-only, which contradicted the calculateEndTime validation that requires a user-supplied endTime for flexible-duration services. endTime is now editable; for fixed/full-day services it is still auto-computed and overwritten on save.
