feat(ops): wire derive_concern into /workflows route (A2)

A2 of docs/specs/ops-workflows-page-refinement/. Adds three new
context keys to the workflows page template render:

- `concerns: dict[str, Concern]` — per-row concern bucket
- `bucket_counts: dict[Concern, int]` — per-bucket counts (all 7
  buckets populated, zero for empty buckets)
- `all_concerns: tuple[Concern, ...]` — stable bucket order for the
  template's chip toolbar

Mirrors the supports_path/default_scopes dict pattern already in
the route — non-invasive, doesn't touch the WorkflowEntry
dataclass. A3a will consume these to render the chip toolbar and
per-row concern pill.

Tests (7):

- Route returns 200, table still renders all canonical workflows
- derive_concern output matches module standalone (spot-checks
  the 6 trade-off boundaries from decisions.md)
- concern_counts sums to total registered workflows
- Smoke checks that existing features (scope picker, tier-map
  chips) still render — A2 is purely additive, no regressions

Stacks on A1 (PR #552). Next: A3a (chip filter toolbar + concern
badge column).
