Sig Select qualifier on the stat-block — green the 3 theme FTs

The qualifier (Elevated/Enlightened/Graven) now renders on the frozen stat-block
stat-face, not just the hover-only text card-face (which image-mode decks hide).
populateStatExtras takes opts.polarity and fills new .stat-face-qualifier--above
/--below slots, mirroring the card-face placement: non-major above the title,
major below it (title gets a trailing comma). Qualifier shares the title's style
per request ("same style as 'Jack of Crowns' below it").

The 3 theme FTs were asserting the qualifier on hover, but the stat-block is
display:none until a card is OK'd (.sig-stage--frozen) — only the card preview
shows on hover. Repointed them to select→OK→freeze, then read the stat-block.
Threaded polarity through the sig + my_sign callers; added 4 Jasmine specs.
