* feat: make Unicode handling in external API calls configurable
- Add DevPreserveUnicodeInExternalCalls config option (default: false)
- Refactor external provider to use NameForExternal() method on auxArtist
- Remove redundant Name field from auxArtist struct
- Update all external API calls (image, URL, biography, similar, top songs, MBID) to use configurable Unicode handling
- Add comprehensive tests for both Unicode-preserving and normalized behaviors
- Refactor tests to use constants and improved structure with BeforeEach blocks
Fixes issue where Spotify integration failed to find artist images for artists with Unicode characters (e.g., en dash) in their names.

* refactor: apply Unicode handling pattern to auxAlbum
Extended the configurable Unicode handling to album names, matching the
pattern already implemented for artist names. This ensures consistent behavior
when DevPreserveUnicodeInExternalCalls is enabled for both artist and album
external API calls.
Changes:
- Removed Name field from auxAlbum struct, added Name() method with Unicode logic
- Updated getAlbum, UpdateAlbumInfo, populateAlbumInfo, and AlbumImage functions
- Added comprehensive tests for album Unicode handling (preserve and normalize)
- Fixed typo in artist image test description
