h3_repr_steering_block goes from a fixed combo (18 candidate blocks) to
free text -- a single block, a range, or a comma list, same syntax as
Repeat block(s) (31-40 / 4,5,6). Each named block steers with its OWN
learned direction from its OWN liked/disliked history at that block --
there is no shared 'the direction', just N independent ones applied at
their own positions in the same forward pass. A block short on rated
data at itself just captures, same as any unnamed candidate block.
CANDIDATE_BLOCKS widened from 18 curated blocks to all 50 -- every block
is now both capturable and steerable, not just the ones on the old grid.
Fixed a pre-existing sync gap: h3_block_repeat_last_steps was never added
to settings_card.py's ownership/defaults tables, breaking two golden-file
tests as soon as they ran (test_settings_card_noise.py).
