fix: artist page resolved "Flay!" to the far more popular "K.FLAY"

The Deezer artist match required only that every query word appear in the candidate name, so
"Flay!" (query word: flay) matched "K.FLAY" (words: k, flay). Sorted by fan count, K.FLAY
(54,822 fans) buried the real "Flay!" (39 fans) — the page showed K.FLAY's fans + top tracks.

Now prefer an EXACT normalized-name match ("flay" == "flay", not "kflay"), falling back to the
loose match only when there's no exact one. Web (detail.js) + Android (ArtistViewModel).
Verified against Deezer: exact match selects the real Flay! (id 12242284, whose top tracks
are actually Flay!). SW ns-v60.
