docs: repair roadmap references after the verification-doc cleanup

The docs cleanup removed Docs/ACCESSIBILITY_VERIFICATION.md and the
results doc, but the v4.9.0 roadmap entry still linked to the checklist
in two places — dead links, and with issue #21 now closed the roadmap is
the only durable record left.

- Both dangling links removed.
- The deferred list was stale in the other direction too: it listed the
  Liquid Glass runtime check as outstanding, but PR #38 ran it on
  simulator alongside the classic-chrome floor. It now names only what a
  Simulator genuinely cannot do — VoiceOver speech and the rotor, Voice
  Control, iPad Full Keyboard Access, Smart Invert — and notes that the
  underlying accessibility metadata is asserted in tests even though its
  spoken output is not.
- Records the Phase 6 verification work itself (#38), which landed after
  the v4.9.0 entry was written: the metadata and screenshot test suites,
  the middle-band Dynamic Type sweep, and the enforced iOS 27.0
  dynamicType finding it caught.

Verified the suppression that finding produced rather than taking it on
trust: it is scoped to .dynamicType plus an exact allowlist of the five
Settings section titles, all of which are plain `Section("…")` with no
app-applied font, so UIKit owns the scaling. Enforcement on
app-controlled text is intact.
