feat: denser market cards — fill the empty space

Each market panel gains a full-width depth-fill meter (depth vs target),
an expanded stat column (spread est, fee/reward/net APR alongside the
existing figures) and a micro-stat stack under the health dial (target,
fill %, ends-in, boost). Fills the previously empty card interior.
