drop safety/availability from scoring, holistic p4 rating, phase-parallel pipeline

safety and availability don't reduce to physics formulas the way
power_density/range_fuel/cost_efficiency do -- they're judgment calls
(risk assessment, infrastructure prevalence), and running them through the
same log-normalize() built for physical quantities produced incoherent
results: safety's raw value is already a "0-1" score, and normalizing it
again turned 0.6 into an unexplainable 0.678 that even the LLM reviewing
it could only cite, never justify (see combo 1540). Removed both from
domain_metric_weights (safety from 4 domains, availability from
urban_commuting) and renormalized the remaining weights to sum to 1.0.

Pass 4 now produces one holistic RATING (LOW/MEDIUM/HIGH) alongside the
existing VERDICT, with safety and accessibility folded in as qualitative
considerations feeding that single judgment rather than scored
separately -- not a checklist of independent numbers. New
qualitative_rating column, filterable in the results UI. Also added
domain name/description to the review prompt so the LLM judges a metric
like range against what the domain actually needs (urban_commuting:
1-50km) instead of generic real-world expectations for the platform
category -- confirmed live on a combo where phi4 had called a 396km range
"limited" by comparing to typical aircraft rather than a domain that
needs 1-50km.

Pass 2 is estimator-only now -- self.llm is never consulted there,
reserved entirely for pass 4. Restructured Pipeline.run() from combo-first
to phase-parallel: each pass now runs to completion across every combo
before the next pass starts, rather than walking each combo through all
four passes before the next combo. This surfaced a real bug: domain-
blocked combos (status stays "valid" by design, not "_fail") were
slipping past a naive status-based skip guard and getting silently
re-processed by pass 2. Fixed with a shared dead-combo check that catches
both generic failures and domain blocks correctly.

Also fixes a results-page display bug found while reviewing a live combo:
the per-metric "position" bar showed raw distance from norm_min without
inverting for lower_is_better metrics, so an excellent cost score (near
the good end) rendered as a ~0%, near-empty bar -- looked bad next to its
own 0.99 normalized score.

Validated live against phi4 (real Ollama calls, not mocked): full-domain
phase-parallel run (2,970 combos, estimator-only p2, 1.6s) followed by a
real pass-4 run (111 reviewed, 11m, 0 crashes, 0 null ratings). Two tests
that relied on the old LLM-driven pass 2 to force deterministic outcomes
were updated to test pass 4's verdict-wiring directly instead. All 100
tests pass.
