Fixed
Slot picker links broken — clicking a time slot navigated to /{username}/{ instead of the booking form.
The minijinja default(value='') filter interpreted the value='' named argument as creating an object {"value": ""} instead of an empty string default. This caused the rescheduleBase JS variable to be truthy even on non-reschedule pages, which broke all slot link URLs.
Fixed by using default('') (positional argument).
