Subject: v4.8.0: Add markdown and PDF export formats

- DomainExportFormat gains .markdown and .pdf (CaseIterable, Identifiable,
  titled), alongside the existing text/csv/json.
- Markdown reuses the existing text-export content verbatim via a line-based
  transform (section "Title\n----" underlines become "## Title", the leading
  title becomes an H1, other lines become bullets), so the two formats can
  never drift apart.
- PDF renders that Markdown as a simple monospaced multi-page document via
  UIGraphicsPDFRenderer (mirrors AuditExporter's existing PDF approach;
  degrades to raw Markdown bytes on non-UIKit platforms).
- Replaced the single/batch/tracked-domains/workflow share call sites' hand-
  written per-format switches with format-agnostic functions
  (exportSingleReportData, exportBatchReportData, exportTrackedDomainsData,
  exportWorkflowData) that delegate straight to DomainReportExporter, removing
  the now-orphaned per-format helper functions those switches used to call.
