fix(portal): disable non-functional stub buttons in customer portal

Reschedule, Cancel, Add Notes, Edit Pet, Archive Pet, and Add New Pet
buttons in the customer portal were UI stubs with no click handlers.
Clicking them did nothing, confusing users. Mark all as disabled with
"coming soon" tooltips and muted styling until the underlying features
(portal reschedule endpoint, pet CRUD portal endpoints) are implemented.

Fixes GRO-166, GRO-167
