Upgrade Shoelace for UI fixes (#1806)

Fixes https://github.com/webrecorder/browsertrix/issues/1802

<!-- Fixes #issue_number -->

### Changes

- Upgrades Shoelace to 2.15.0 for UI fixes including #1802 (See
https://github.com/shoelace-style/shoelace/blob/v2.15.0/docs/pages/resources/changelog.md)
- Refactors custom components that extend Shoelace components so that
shared shoelace `componentStyles` are included properly
