feat(ops): chip filter toolbar + concern badge column + JS (A3a)

A3a of docs/specs/ops-workflows-page-refinement/. Mirror of the
Specs page A3a (PR #535) for visual + behavioral consistency
across the dashboard's two filtered-list surfaces.

Surface added:

- Chip filter toolbar above the workflows table (7 concern buckets
  + search input). All 7 chips active by default — unlike Specs
  page's Complete-off default, no Workflows concern is structurally
  "noise."
- Per-row concern pill in a new column between Name and Tier map.
  Color-keyed off the same `bucket-<name>` class as the toolbar
  chip for visual continuity.
- `data-concern` attribute on each <tr> for the JS filter.

Files:

- src/attune/ops/templates/workflows.html — toolbar + column +
  conditional script load
- src/attune/ops/static/js/workflows_refined.js — chip toggle,
  search, empty-state, init. Pure DOM manipulation; no fetch.
  Exposes window.__attuneWorkflows for source-grep tests.
- src/attune/ops/static/css/main.css — `.workflows-toolbar` block
  parallels `.specs-toolbar`. Per-concern colors (review purple,
  test green, docs orange, refactor pink, audit amber, meta cyan,
  other neutral) applied to BOTH the toolbar chip when active AND
  the per-row pill.

Tests (16 new):

- tests/unit/ops/test_workflows_refined_js.py — source-grep tests
  mirroring the test_specs_routes.py::test_specs_refined_js_* and
  test_runner_js_parsing conventions. Catches accidental removal
  of:
  - window.__attuneWorkflows namespace export
  - 7-bucket VALID_BUCKETS set
  - state / applyFilters / setChipState / init API surface
  - DOM selectors (`.workflows-table tbody`, `.workflows-toolbar
    .chip[data-bucket]`, `#workflows-search`)
  - Empty-state message text
  - Template references workflows_refined.js

No regressions on existing Workflows page features (runner.js,
bulletin.js, scope picker, recent runs strip, discovery-sweep
chips). All 7 existing test_workflows_route_concerns tests pass
unmodified.

Stacks on A2 (#553). Next: A3b (kebab action menu) and A3c (URL
param parsing).
