Remember type hierarchy expansion without flashing on return

[mattdawkins]

The annotation type list forgets expanded parents and collapsed branches when the viewer is remounted, and metadata reloads reset it to compact mode. Returning from another page can therefore flash a different hierarchy view.

Persist presentation state per sequence and restore it synchronously before rendering. Metadata hydration no longer resets it. Sidebar and bottom layouts, and cameras of the same sequence, share the preference. Other sequences and group lists retain independent views. A bounded local store remembers the last 100 views; unavailable browser storage falls back to memory.

Category definitions, checked types, confidence thresholds, and annotation timelines are unchanged.

Validation: 60 hierarchy/list/storage tests pass, including immediate first-render assertions after remount, metadata reload, dataset switching, persistence across store recreation, malformed storage, and storage failures. ESLint and TypeScript checks pass.

An Electron rendering check remounted a bottom hierarchy panel, reloaded its metadata, and observed only the saved expanded-parent view while retaining its collapsed branch. The combined viame/main changes passed 298 tests and desktop/web production builds.
