test(integrations/client/packages): batch 2-4 unit coverage + zip-slip guard extraction

Batch 2-4 of the test-strategy rollout. Test-only except one minimal,
behaviour-preserving extraction in file.utils.ts. All suites green:
server 82 suites/836+1todo, editor-ext 86, mcp 270, client (new files) 86.

integrations (server):
- file.utils.ts: extract pure `isEntryPathSafe(entryName, targetDir)` from
  extractZipInternal so the zip-slip/path-traversal guard is unit-testable;
  call site rerouted, behaviour identical (only a warn-message string merged).
- file.utils.zip-safety.spec.ts: traversal/strip/__MACOSX/prefix-confusion
  cases (mutation-resistant: fails if containment loses the path.sep).
- import-formatter / import.utils / table-utils / export utils / import.service
  extractTitleAndRemoveHeading: pure import/export transforms, Notion/XWiki
  formatting, table colspan widths (idempotent), slug/link rewriting.

client:
- safeRedirectPath: open-redirect guard, every reject branch independently.
- buildChatMarkdown (fence anti-breakout), label-colors, normalize-label,
  share tree build, page URL builders, notification time-grouping (fake clock).

packages:
- editor-ext: deriveFootnoteId golden table, parseHtmlEmbedHeight crafted
  values, orphan footnote extraction.
- mcp: deriveFootnoteId parity (drift guard vs editor-ext), applyTextEdits
  idempotency + cross-block replaceAll, diffDocs/summarizeChange on reorder.

Reviewed (APPROVE): extraction behaviour-preserving, assertions mutation-resistant.
