Persist Last Sorting State in Assets View

[rrpolanco]

Zennotes 2.17.0 introduced sorting the assets view by its columns. This works well, but the sorting is not sticky. I.e. if I sort the assets view by Modified and then click away from the view, the sorting is lost when I come back to the view.

Fixed in 6e1a44c (shipping in 2.18.0). Thanks for following up on this one, the sorting was genuinely only half-finished.

What was happening: the sort you picked by clicking a header was component-local state. The Assets view unmounts the moment you navigate away, so the choice went with it and you came back to Name ascending every time.

The fix: sort is now a real preference, so it sticks. It survives leaving and returning to the view, and it survives quitting and reopening the app. It follows the same shape as the note sort order: a single <column>-<dir> value written to config.toml as:

[view]
asset_sort_order = "modified-desc"  # Assets view sort: name | used | type | size | modified, each -asc or -desc

It also honours the View settings scope setting, like the other view preferences: global by default, or per-vault if you have that turned on, so different vaults can keep different Assets sorts.

Verified in the desktop app: sorted by Modified, opened a note, came back to Assets, and the column plus its arrow were still there; same after a full restart.
