Perf-1: Eliminate duplicate permission query on task update.
get_effective_task_permission now returns (effective, project_level)
tuple so the SEC-P02 allowlist check reuses the project-level
permission from the first call instead of querying again.
Perf-2: Memoize member permission lookup in ProjectDetail. Replace
3 inline acceptedMembers.find() calls with useMemo-derived
myPermission and canEditTasks.
S-06: Pass members/currentUserId/ownerId/canAssign to mobile
TaskDetailPanel (was missing — AssignmentPicker never appeared on
mobile).
S-08: Add missing selectinload(TaskComment.user) to subtask comments
chain in _task_load_options. Subtask comment author_name was always
null.
W-01: useDeltaPoll stores queryKeyToInvalidate in a ref to prevent
infinite re-render if caller passes inline array literal.
