feat(combat): play the round a beat at a time with attack and hit frames

The server resolves a whole round in one call, so both blows used to land
at the same instant. The page now keeps its own view of the combat and
plays the round back: the swing animates, the monster's HP and log line
land, then after a beat the monster strikes and the player recoils.

Both animations are six-frame sprite sheets driven by steps(6), which is
why the phase durations mirror the stylesheet.

The status row reflows on the stage's own width via a container query —
the side rails can squeeze it narrow while the viewport is still wide,
which previously overlapped the round marker with the player's name. The
component-style budget moves to 12kB to fit this screen's stylesheet.
