Refs OpenConceptLab/ocl_online#299

Summary

Replaces the Mapper's public-preview announcement with the subscription-dates banner that is going live on openconceptlab.org, so the apps and the site say the same thing.

• New announcement id subscription-dates-2026-10 (the same id as the community site), so visitors who dismissed the preview banner see this one.
• Text (en/es/zh): "Subscriptions open November 1." / "Existing accounts using premium features have a grace period until December 1."
• Two links instead of one, separated by " · ", each opening in a new tab:
  • "Learn more": the letter to the OCL community (existing announcement.link_label, unchanged)
  • "See pricing": openconceptlab.org/pricing (new announcement.pricing_link_label in en/es/zh)
• Both URLs carry utm_source=oclmap&utm_medium=banner&utm_campaign=subscription_dates. MAPPER_ANNOUNCEMENT_URL in src/common/constants.js becomes MAPPER_ANNOUNCEMENT_LETTER_URL and MAPPER_ANNOUNCEMENT_PRICING_URL.
• Each link has whiteSpace: 'nowrap', so a label doesn't break mid-label when the banner wraps on narrow screens.

The banner doesn't record GA events today, and this PR doesn't add any.

Test Plan

• ./node_modules/eslint/bin/eslint.js src --ext .jsx,.js: clean
• npm run test:all: 401 unit + 6 integration tests pass (no existing banner test; the suite runs .test.js under node --test, which doesn't cover JSX components)
• Locale bundles parse, and announcement.* has the same keys in en/es/zh
• After deploy: banner shows the new text in en/es/zh, reappears for someone who dismissed the preview banner, and both links open the right page in a new tab
• On a phone-width viewport, "Learn more" and "See pricing" each stay on one line

Notes

Don't merge until Jon's go; production deploy is manual.

Clean—no actionable findings.

• Unique, stable React keys; both links render in order with single-line labels.
• New announcement ID correctly resets dismissal; dismissing persists the new ID.
• Links remain keyboard accessible and use target="_blank" with rel="noopener noreferrer".
• Spanish and Chinese accurately convey the dates and grace period.
• URLs and UTM tags match the requested destinations and app attribution.
• JSON parsing, JSX/JS syntax checks, and git diff --check passed. No stale constant references found.
