docs(audit): Client.UI.md — accuracy pass

Browse Source 
CODE-REALITY fixes (file:line evidence):
- Read/Write tab write description was wrong: claimed the service reads
  current value first to determine the target type before writing.
  ReadWriteViewModel.WriteAsync (ReadWriteViewModel.cs:97-113) calls
  WriteValueAsync directly with the raw string — no pre-read.
  The type-inferring read-before-write lives only in the Subscriptions
  tab write dialog (SubscriptionsViewModel.ValidateAndWriteAsync).
  Button label is also "Write", not "Send" (ReadWriteView.axaml:35).
- Settings save timing was incomplete: MainWindowViewModel.DisconnectAsync
  (MainWindowViewModel.cs:309) calls SaveSettings() on disconnect too;
  doc said only "after successful connect and on window close".

STRUCTURAL: no rows in links-report.md for this file.
STALE-STATUS: no stale-status language found.
INLINE COMPLETENESS: no inventory gaps found.
