Fixes to v1.0.7 (#1953)

## Description
Collection of minor bug fixes for `v1.0.7`

- Fixes a possible race condition crash when navigating to the search
page
- Uses friendlier error message when login fails due to parental
restrictions (based on
[`jellyfin-web`](https://github.com/jellyfin/jellyfin-web/blob/v10.11.11/src/controllers/session/login/index.js#L38-L41))
- Don't re-sort search results by name, just by relevance scoring
- Consume the key event when dim is active (ie if the screen is dimmed,
pressing a key will un-dim and not perform another action)
