feat: add booking time ranges and repeating series

+    The shared body of both booking modals. Which fields exist is decided by the controller
+    (the edit modal removes date and the recurrence fields), so everything here is guarded with
+    `is defined` rather than duplicated into two templates.
+
+    Show/hide is Stimulus, not htmx: toggling a fieldset needs no server round trip, and the
+    house rule keeps purely client-side behaviour out of htmx.
