MailApp v1.7.54

feat: silent (server) update refreshes update-service.ps1 too; script v2

- NSIS customInstall: on silent install, copy only update-service.ps1 into the
  ProgramData service folder (if service present) without stop/reinstall; the
  running service self-restarts on the file-hash change. Interactive install
  still does the full service (re)install.
- Bump service $ScriptVersion to 2.

feat(admin): client actions via AJAX (no page reload, keeps scroll)

Обновить/Отменить/удалить for a client now POST via fetch and refresh only the
table; the server returns JSON for ajax=1 requests instead of a PRG redirect.
No more scroll jump to the top.

fix(service): relaunch task no longer kills the app after 10 min

The MailAppLaunch relaunch task had ExecutionTimeLimit=PT10M, so Task Scheduler
terminated the relaunched GUI after 10 minutes (only after service updates;
manual launch was unaffected). Set PT0S (no limit).
