feat(a11y/#1380): colorblind sim overlay (Brettel/Vienot) + reset-to-Wong button (#1600)

Implements the two deferred a11y stretch goals from #1361 / PR #1378.

## What

1. **Brettel/Vienot 1997 dichromatic simulation overlay** —
`public/index.html` ships inline `<svg>` defs with `<filter
id="cb-deut|cb-prot|cb-trit|cb-achromat">` using `feColorMatrix`.
Activation rule: `body[data-cb-sim="X"] { filter: url(#cb-X); }`.
`public/customize-v2.js` renders a radio group
(off/deut/prot/trit/achromat) under the existing CB preset section.
Preview-only — **not persisted**, per the issue spec.
2. **Reset to default Wong button** — `data-cv2-cb-reset` button that
calls `MeshCorePresets.applyPreset('default')` and removes
`localStorage["meshcore-cb-preset"]`.

Two helpers exposed on `window._customizerV2` for unit-test drive:
`applyCbSim(id)` and `resetCbPreset()`.

## TDD (red → green)

- **Red:** `49155723` — `test-issue-1380-cb-sim-overlay.js` +
`test-issue-1380-cb-reset-button.js`. Both load `customize-v2.js` and
(for reset) `cb-presets.js` in a vm sandbox; failure is assertion (not
compile).
- **Green:** `5d8f3c1f` — both tests pass (21 + 7 assertions).

## Files changed

- `public/index.html` — inline SVG `<defs>` + 4-rule `<style>` block.
- `public/customize-v2.js` — render fns `_renderCbSimSelector` +
`_renderCbResetButton`, change/click handlers, helper exports.
- `test-issue-1380-cb-sim-overlay.js` (new) — string-asserts on
index.html SVG filters / CSS rules / customize-v2 hooks +
vm.createContext drive of `applyCbSim`.
- `test-issue-1380-cb-reset-button.js` (new) — vm.createContext seeds
`meshcore-cb-preset=trit`, calls `resetCbPreset()`, asserts storage
cleared + `body[data-cb-preset="default"]`.
- `test-all.sh` + `.github/workflows/deploy.yml` — register both tests.

## Out of scope

- No new preset palettes (locked from MVP).
- No persistence for the sim overlay (preview-only per spec —
`localStorage` intentionally untouched by sim radio).
- No colorblind-sim JS library — pure inline SVG `feColorMatrix`.

Browser verified: filter rule matches via CSS sandbox; visual
confirmation deferred to operator (single-tab radio, no fetch). E2E DOM
assertion lives in the cv2 vm tests.

Fixes #1380
