Ballot question follow-up fixes

[tripledoublev]

Summary

This PR includes changes for the ballot-question demo follow-up fixes and includes the additional cleanup needed to make the BQ perspective/testimony-count behavior and BQ testimony display consistent with existing bill patterns.

Changes

• Remove all BQ perspectives from the Browse Testimony page

  • Excludes testimony with a ballotQuestionId from the Typesense testimony index.
  • Updates search index versioning so filter/indexer logic changes force a new collection version and alias rollout instead of silently reusing the old index.
  • Important operational note: existing indexed BQ testimony/perspectives will only disappear from Browse Testimony after the Typesense/admin reindex path runs.

• Fix the way ballot questions display on Followed Content so that it shows the question number and title

  • Updates the followed ballot-question card to show the ballot-question label and title/description instead of the weaker fallback display.

• Perspective count does not automatically increase after submitting

  • Replaces the page-refresh workaround with persisted ballot-question testimony counters.
  • Adds testimonyCount, endorseCount, neutralCount, and opposeCount to ballot-question documents.
  • Reuses the testimony count update path on publish/delete so ballot questions now update on write, the same way bills do.
  • Updates the ballot-question detail and browse pages to read stored counters, with a safe fallback for legacy docs that have not been backfilled yet.
  • Adds an admin backfill script for existing ballot questions and updates ballot-question YAML sync so live counters are preserved during future syncs.

• Remove duplicated copy “share your perspective” on the button and in the component text in the Your Perspective component

  • Makes the compact panel title optional for the ballot-question CTA path so the duplicate heading is removed.
  • Restores the expected Complete button styling.

• Committee hearing should open in new tab, and link format should reflect that (diagonal arrow)

  • Opens committee-hearing links in a new tab and updates the UI to show the external-link arrow.

• On BQ Perspectives tab, retain the small text saying “review testimony on the related bill” and remove the larger callout that says “submit”

  • Keeps the small explanatory copy and removes the redundant larger submit callout.

• Viewing “BQ testimony” on its own page shows the title of the bill but the side panel shows ballot question detail; it should show the title of the BQ

  • Loads ballot-question data into the testimony detail page state when the testimony belongs to a ballot question.
  • Updates the testimony header and side-panel policy actions to show the ballot-question title instead of the bill title for BQ testimony.

• Include Ballot Questions in the Newsfeed updates

  • Adds ballot questions to the Newsfeed filter set.
  • Wires ballot-question fields through the Newsfeed card components.
  • Adds the ballot-question-specific card title/following-match path so the follow context renders correctly.
