* feat(pages): migrate accessibility page to CMS - Update footer link from /accessibility to /p/accessibility - Remove hardcoded accessibility page and test * fix(ci): remove /accessibility from Lighthouse URLs The hardcoded /accessibility page is replaced by the CMS page at /p/accessibility which requires the API backend. Since the Lighthouse CI only runs the Next.js standalone server, CMS pages can't be tested. Accessibility coverage for CMS pages is handled by vitest-axe tests. * fix(post): show feedback when posts are held for moderation Previously, held posts appeared to succeed silently -- users saw "Reply posted" or got redirected but their content never appeared. Changes: - Parse API error responses as JSON, show human-readable messages instead of raw JSON strings (fixes #75) - Add CreateTopicResponse/CreateReplyResponse types with moderationStatus field (fixes #74) - Show "pending review" message when topic/reply is held - Detect "Onboarding required" errors and trigger the onboarding modal instead of showing a raw error (fixes #76) - Extract throwApiError() helper for consistent error handling - Update tests for new error message format Fixes barazo-forum/barazo-workspace#74 Fixes barazo-forum/barazo-workspace#75 Fixes barazo-forum/barazo-workspace#76
