fix(coder): drop human_inbox view before dropping tasks columns

The audit-cleanup migration dropped tasks.feature_values/worktree_path, but
human_inbox is `SELECT * FROM tasks` and pins every column, so the DROP COLUMN
failed (2BP01) on any existing DB and crash-looped boocoder on boot. Drop the
view, drop the columns, then recreate it — idempotent on fresh and existing DBs.
