Josh Patterson 36833fdad1 so-grid-highstate: emit single-line pillar JSON and skip empty tiers
Two defects surfaced testing BRANCH=asasoup soup on a manager+heavynode grid:

1. The tiered-pass actions JSON was built from a multi-line heredoc. salt parses
   'pillar=<value>' kwargs with a non-DOTALL regex, so the embedded newlines made
   salt-run treat the whole token as a positional saltenv -- 'No matching salt
   environment for environment pillar={...}' -- and the highstate never ran, leaving
   the heavynode on the old version. Emit the actions JSON on a single line (matching
   how so-push-drainer's json.dumps payload already works).

2. orch.push_batch's salt.state step reports 'No minions returned' (a failure) for a
   tier whose compound target matches nothing, so any grid lacking a role (no receiver,
   small grids) always logged a warning and returned rc=1 even when every present node
   converged. Pre-check each tier with 'salt -C <tgt> --preview-target' and include only
   tiers that match >=1 minion; exit cleanly if none match.

Verified live: heavynode highstated 3.2.0 -> 3.3.0 (427 states, 0 failed) and a
follow-up run skips the empty receiver/remainder tiers with rc=0.
