Bug 1 — a calendar shared with me stayed visible after unchecking it: the hide
was a one-shot cache filter the server undid on refetch. Add a per-device
hidden set (localStorage 'hiddenLocalCalendars'), honoured in filterEvents
(normal view) and used to drive the checkbox state, so it survives refetch/reload.
Bug 2 — in the group combined view, other members' events showed edit/delete and
403'd on save. The combined endpoint now emits read_only (editable = the group
calendar OR my own events), via a read_only param threaded through
build_local_event_dict/expand_recurring_local. The event popup and edit modal now
treat read_only events as read-only (copy still allowed). Test added.
