Security review: F34 client library upgrades approved for 8.3.0

John's decision: DOMPurify to 2.5.x and Vuetify to the latest 2.x (2.6.16 as the
fallback if 2.7 does not build on Node 12.22.9), as an exception to the
front-end dependency rule, each proven by a full client build and Cypress.

 - **Security review F1, fixed in 8.3.0:** the LAN/IIS (`dist\assets\lan-install-config.json`) and Linux server (`dist\assets\linux-server\config.json`) templates ship `AYANOVA_JWT_SECRET` set to a placeholder that is printed in the manual. The manual tells users to change it (optional on Linux), but an install that keeps it signs logins with a publicly known secret. Consider generating a random secret at install time or refusing to boot with the placeholder. Pre-existing
 - Standalone and LAN installers share the same Inno Setup `AppId` (`{B2BB79DB-0690-497C-B92B-955F7B468429}`) although they are different products (`AyaNova` vs `AyaNova server`): installing one over the other would be treated as the same application. Pre-existing; not tested. Both also install to the same folder (`{autopf}\ayanova`) and use port 7575, so the two flavours could never sit side by side on one machine anyway; the shared `AppId` only changes what happens when one flavour is installed **over** the other (e.g. an evaluator moving from standalone to LAN on the same PC): Setup treats it as an upgrade of the same program. Changing either `AppId` now would make that flavour's next installer miss existing installs (second Add/Remove entry over the same folder). Standalone is thought to be used almost only for evaluation (John). **John, 2026-10-23: keep both `AppId`s as they are**; the Windows install pages now say only one type per computer, uninstall the other first (backup and restore to switch)
 - Sockeye 8.1.0 has the NLog 6 archive naming problem fixed here for AyaNova: archives are `log-sockeye_NN.txt`, old `-0` to `-8` archives are never deleted, and its log viewer still sorts by name (it also filters on `ayanova.txt`, not `sockeye.txt`, so the current file is listed twice). Same fix applies: `ArchiveSuffixFormat = "-{0}"` and the date sort
-- **Security review: customer contact isolation (John, 2026-10-23: urgent, fixed with the "next release" cases before 8.3.0; case numbers to come).** Findings F13 to F17 in `devdocs/modernization/SECURITY-REVIEW.md`, confirmed on the local server as a seeded customer contact: any customer's work order by id (and, by code, its customer report and attachments); other customers' service requests; the full customer list with phones and emails through pick lists; the whole service schedule; notification subscriptions created for another user. Hosted and self-hosted perpetual installations are equally important. Fix direction in the review: block customer-type users by default except the routes the customer UI uses, then add a "belongs to my customer" check to each allowed route that takes an id. F5 (2FA without password), F1 (placeholder JWT secret) and F18 (pick-list search text in SQL) are fixed in 8.3.0 too (John, 2026-10-23). **8.3.0 is not released until every security review finding is fixed or explicitly accepted by John** ("all holes must be plugged"); the review's remaining passes therefore come before the release

 - **SuperUser can be deleted (serious, pre-existing, own case; John's decision 2026-10-23: fixed with the other "next release" cases before 8.3.0 ships, not under the port):** `UserBiz.ValidateCanDelete` (`biz/UserBiz.cs:1055`) only refuses a delete when the user has related records; nothing protects user id 1, although updates to it are blocked (`UserBiz.cs:946`). On the droplet, whose sample data left SuperUser with no related records, the integration test `UserWithActivityShouldNotBeDeleteable` (`DELETE User/1`) succeeded and removed the account; `AYANOVA_SET_SUPERUSER_PW` cannot bring it back (it only resets an existing user 1). Same code in 8.2.4; likely also why `superuser` could not log in on the reused local database at the first baseline attempt. Any user with delete rights on Users can do this
 - `RunProgram.Run` (and its `RunWindows`/`RunLinuxShell`/`RunOSX` helpers) has no callers since the backup moved to `RunNoShell`. It runs through `cmd.exe /C` or `/bin/sh -c` and logs its full command line on error: delete it rather than reuse it
 - **Own case after the port (John): automated provisioning from Sockeye.** Goal: from a trial subscription server request, one menu item in Sockeye (after John's manual approval) provisions the whole server through the DigitalOcean API, ready for login: droplet, DNS, firewall, setup, licence. Replaces today's manual steps (header comments of the setup script), which are slow and error-prone. Not part of this port
