When a story/task/project/milestone has duplicate strings in a user-editable list (tags, acceptance criteria, deliverables), the UI panics and freezes with:

panicked at dioxus-core-0.7.4/src/diff/iterator.rs:107:17:
assertion left == right failed: keyed siblings must each have a unique key

The affected lists use each item value as its Dioxus key, so repeats collide.

Repro: create a story with acceptance criteria ["a", "b", "a"], open its detail, click Delete → WASM unreachable trap, whole island freezes.

Affected:

stories/views/story_detail_view.rs — acceptance criteria
sprints/views/milestone_detail_view.rs — deliverables
tasks/views/task_detail_view.rs, tasks/views/task_item.rs — tags
projects/views/project_detail_view.rs — tags

Fix: key by enumerate index instead of value.
