Report simulations as what they would remove, list each account once, and show the release version

[rodchristiansen]

Three fixes from verifying v2026.10.06.2019.

Simulation wording and duplicates

• A simulation logged "4 user(s) removed" and "Removed 1 orphaned recycle bin(s)" though it removes nothing. Those lines, and the per-user scheduled task count, now say "would remove" when simulating.
• An enabled local account with no profile was evaluated by the main pass and again by the orphan pass, so a simulation listed it twice. The main pass now evaluates only accounts with a profile. A profile-less account is left to the orphan pass, which dates it by password age; the main pass had no profile folder to date it by and used the current time.

Deleting an account with no profile

• DeleteProfileW was called even when the account had no ProfileList entry. It failed with error 2 and logged a warning before falling back. It is now skipped when there is no profile. The fallback only logs a registry entry as deleted when one existed.

App version

• The Managed Users Cleanup Prefs header showed the build time. It now shows the informational version stamped from the tag, zero-padded, with the +<commit> suffix dropped, e.g. 2026.10.06.2019.

Tests: new RunReportingTests cover the wording, the de-duplication, the DeleteProfileW guard and the version text. All 86 tests pass locally.
