fix: seed bb_phase=1,pct=0 at surface_validate start (1.0.0-45)

Previously the parser only wrote bb_phase to the DB when state
*changed* — so for the first several minutes of a 14 TB burn-in
(before badblocks emits its first 'X% done' line), bb_phase stayed
NULL and the drawer's per-pattern meters didn't render at all.
Looked broken to operators.

Now we write phase=1, phase_pct=0 immediately on stage entry. The
parser keeps overwriting on every subsequent tick. Drawer shows
empty meters with 0xaa label highlighted blue from t=0.
